The researchers from a study interviewed two random samples, one in 2015 and one in 2018. Both samples were asked "Have you read a print book in the last Question Help year?" Use the accompanying results from the study to complete parts (a) through (c). Read a print book 2015 2018 Total Yes 1195 726 1921 1372 605 1977 2567 No 1331 Total a Find and compare the sample proportions that had read a print book for these two groups. The sample proportion of the 2015 subjects that read a book within the last year is 622 The sample proportion of the 2018 subjects that read a book within the last year is 694. (Round to four decimal places as needed.) The sample proportion for 2015 is less than the sample proportion for 2018. b. Find a pooled estimate of the sample proportion. A pooled estimate of the sample proportion is (Round to four decimal places as needed) c. Has the proportion who read print books increased? Find the observed value of the test statistic to test the hypotheses Ho P, = P2 and H, P,

Income Tax and the IRS. In 2010, the Internal Revenue Service (IRS) sampled 308,946 tax returns to obtain estimates of various parameters. Data were published in Statistics of Income, Individual Income Tax Returns. According to that document, the mean income tax per return for the returns sampled was $11,266. a. Explain the meaning of sampling error in this context.b. If, in reality, the population mean income tax per return in 2010 was $11,354, how much sampling error was made in estimating that parameter by the sample mean of $11,266?c. If the IRS had sampled 400,000 returns instead of 308,946, would the sampling error necessarily have been smaller? Explain your answer.d. In future surveys, how can the IRS increase the likelihood of small sampling error?
