Chapter 6: Q.31 (page 357)

Better readers?(1.3) Did students have higher reading scores after participating in the chess program? Give appropriate statistical evidence to support your answer.

Short Answer

Expert verified

Yes, students are getting higher marks.

Step by step solution

01

Step 1: Given information

It is given in the question that,

The graphs and numerical summaries below provide information on the subjects鈥� pretest scores, posttest scores, and the difference (post 鈥� pre) between these two scores.

02

Explanation

The presented boxplots of Pre and Post are overlapping, and the difference between Post and Pre is decreasing below 0, implying that there is no increase in all students' scores after participating in the chess programmes.

It's also worth noting that the median and mean differences are not negative, implying that the scores have changed. As a result, it is possible to conclude that students' results improve after participating in chess programmes, however not for the majority of pupils.

The length in inches of a cricket chosen at random from a field is a random variable Xwith mean 1.2inches and standard deviation of 0.25 inches. Find the mean and standard deviation of the length Y of a randomly chosen cricket from the field in centimeters. There are 2.54 centimeters in an inch.

Toss 4times Suppose you toss a fair coin 4times. Let X=the number of heads you get.

(a) Find the probability distribution ofX.

(b) Make a histogram of the probability distribution. Describe what you see.

(c) Find P(X鈮�3) and interpret the result.

54. The Tri -State Pick 3Refer to Exercise 42. Suppose 365
(a) Find the mean and standard deviation of your total winnings. Show your work.
(b) Interpret each of the values from (a) in context .

Checking for survey errors One way of checking the effect of undercoverage, nonresponse, and other sources of error in a sample survey is to compare the sample with known facts about the population. About 12% of American adults identify themselves as black. Suppose we take an SRS of 1500American adults and let Xbe the number of blacks in the sample.

(a) Show that Xis approximately a binomial random variable.

(b) Check the conditions for using a Normal approximation in this setting.

(c) Use the Normal approximation to 铿乶d the probability that the sample will contain between 165and 195blacks. Show your work.

Benford鈥檚 law and fraud Refer to Exercise 13. It might also be possible to detect an employee鈥檚 fake expense records by looking at the variability in the first digits of those expense amounts.

(a) Calculate the standard deviation 蟽Y. This gives us an idea of how much variation we鈥檇 expect in the employee鈥檚 expense records if he assumed that first digits from 1 to 9 were equally likely.

(b) Now calculate the standard deviation of first digits that follow Benford鈥檚 law (Exercise 5). Would using standard deviations be a good way to detect fraud? Explain.
