Mind on statistics 5th edition pdf download
Questions 1 to 3: Suppose you were to read about a study showing that mind on statistics 5th edition pdf download who sleep less than five hours a night have twice as much risk of a premature death as people who sleep seven or eight hours a night.
Questions 4 to 6: A randomized experiment was done by randomly assigning each participant either to walk for half an hour three times a week or to sit quietly reading a book for half an hour three times a week.
Questions 21 to The result of an Internet poll was reported as evidence that most people believe the pledge of allegiance is constitutional. The poll was conducted by posting a notice on a website and asking people to respond. The results were based on people who responded. Questions 28 and In a study of patients who had a heart attack, patients were randomly assigned to receive one of three treatments: aspirin alone, warfarin alone, or aspirin plus warfarin. The results showed that mind on statistics 5th edition pdf download The difference between the aspirin and warfarin groups was statistically significant, mind on statistics 5th edition pdf download, while the difference between the warfarin and aspirin plus warfarin group was not statistically significant.
Questions 34 to A five number summary for hours studied in a week were 5, 12, 14, 18, and Questions 45 to In a Census Bureau report, the total number of households and the number of households with a married couple and their own children were reported for the years and for The results are given below:.
Year Number of households with married couple. Questions 48 to The results of 2, people on trial for murder are shown below by the race of the victim black or white and the verdict death penalty yes or no.
These results were used in a Supreme Court trial on behalf of a defendant. Descriptive statistics for the number of letters that could be written using the dominant and non-dominant hand. Descriptive statistics for number of minutes spent talking on the phone for male and female students. Can you conclude that sleeping the shorter hours causes a higher risk of premature death? No, because the result was clearly based on an observational study.
Yes, because the result was clearly based on a randomized experiment. No, because the baseline risk of premature death is not given. Medications a person is taking.
The amount of alcohol a person drinks in the evening. The amount of stress a person is under in their work. The amount of sleep a person gets per night. This is a randomized experiment rather than an observational study because blood pressure was measured at the beginning and end of the study. The two treatments in this study were walking for half an hour three times mind on statistics 5th edition pdf download week and reading a book for half an hour three times a week.
If a statistically significant difference in blood pressure change at the end of a year for the two activities was found, then it cannot be mind on statistics 5th edition pdf download that the difference in activity caused a difference in the change in blood pressure because in the course of a year there are lots of possible confounding variables.
A dotplot displays all of the individual responses while a five-number summary does not. A five-number summary displays all of the individual responses while a dotplot does not. Both a dotplot and a five-number summary display all of the individual responses.
Neither a dotplot nor a five-number summary displays all of the individual responses. The five numbers in a five-number summary are the lowest value, mind on statistics 5th edition pdf download, mean, median, mode, and the highest value.
A student proposes using the median of the numbers instead and calls this medGPA. A student has taken five courses all an equal number of credit hours and the grades were A, A, F, B, A.
The usual GPA for these grades is 3. Should the student prefer using the median medGPA? A pop quiz in a class resulted in the following eight quiz scores: 0, 60, 66, 78, 82, 96, 98, The five-number summary for these test scores is 0, 63, 80, 97, Which of the following is true about the use of sample surveys? Everyone in the population must also be in the sample. Data from people in the sample are used to gain information about the population.
Data from people in the population are used to gain information about the sample. The population is a subset of the sample. Which of the following is true about the margin of error for the most common types of surveys? If the number of individuals in the sample were to be substantially increased, the margin of error would decrease. If the number of individuals in the sample were to be substantially decreased, the margin of error would also decrease.
If the number of individuals in the sample were to be substantially increased, the margin of error would not change, mind on statistics 5th edition pdf download. If the number of individuals in the sample were to be substantially decreased, the margin of error would not change. If a magazine sends a survey to a random sample of 10, of its subscribers but only of them return the survey, mind on statistics 5th edition pdf download, the sample results may not be representative of the population of subscribers because they used a self-selected sample.
In the study described in Case Study 1. Only 4. This means that the margin of error for the mind on statistics 5th edition pdf download was 4. The moral of the story was cause-and-effect conclusions can generally be made in an observational study.
An organization would like to conduct a survey of a sample of their membership to make conclusions about the entire membership. Given that they have a limited budget, they should focus their attention on getting as large a sample as possible, even if they are all volunteers. One of the common elements of the eight case studies in Chapter 1 is in each case, a randomized experiment is described. One potential problem with this headline is motivated students could have both taken calculus in high school and have a high GPA 3.
All were married and trying to get pregnant. It was reported that for every 2 percent increase in the amount of calories a woman got from trans fats instead of carbohydrates, her risk of infertility increased by 73 percent. Is the following statement true or false? The results of the study show that the American public was evenly divided on whether pilots should be armed or not. In a study of advanced colorectal cancer, patients were randomly assigned to receive either a high dose of Vitamin C or placebo.
The study concluded that Vitamin C was not effective in the treatment of advanced colorectal cancer because none of the patients with disease showed any improvement in the two groups. The cause and effect conclusion might be justified because randomization was used. The statistically significant difference between the aspirin group The non-statistically significant difference between the warfarin alone group An Islamic survey conducted by the Gallup organization consisted of a random sample of mind on statistics 5th edition pdf download, people living in 9 predominantly Islamic countries.
The population represented by this sample was all Muslims in the world. A random sample of 1, adults aged at least 18 years and living in the 48 contiguous states i. The interviews were done over the telephone. The population represented by this sample was all adult Americans in the 48 contiguous states living in a household with a phone. If the sample size for a poll increases from people to people, the margin of error increases by a factor of 4, i.
This difference was reported as statistically significant. The statistically significant difference between male and female students means that the difference between the two rates He has been collecting data for years. The sociologist has looked at relationships between many of the variables and tested if there were differences between the different fields. The only difference that was found to be significant was the mean age of social science instructors and the mean age of natural science instructors.
What is most likely the cause of this one significant result? A statistically significant finding does not necessarily have practical significance or importance. When a study reports a statistically significant finding, we also need to find out the magnitude of the result.
A change in the rate or risk of occurrence of something is only useful when the base rate or baseline risk is reported as well. When you read about a reported relationship or difference, you also need to find out how many different things were tested. The more tests that are done, the more likely it is that a statistically significant difference is a false positive that can be explained by chance. Sample sizes are dependent on population sizes.
So, in order to give reasonably accurate information about a population of many millions, we have to take a sample of many thousands. In the baseball player Barry Bonds hit a record 73 home runs. During that year, mind on statistics 5th edition pdf download, he was at bat times.
In the baseball player Barry Bonds had base hits out of at bats. Inthe total number of deaths among American men aged was 10, with 3, deaths among American women aged years. The total numbers of year olds were 8.
Calculate the death rates perfor year old men and women. Was the rate for men higher or lower than for women? Calculate the approximate margin of error for mind on statistics 5th edition pdf download survey.
Inwhat percentage of households consisted of a married couple with children? Both newspapers reported correct figures; explain why it was possible for them to come to opposite conclusions. Which conclusion do you think is more descriptive of the trend? What are some confounding variables that might also explain the observed difference in percentages of death penalties for cases where the victim was white versus black?
The times in seconds of the 8 finalists are listed below. Drawn below are two dotplots displaying the heights in inches of 94 females and 77 males.
