Homework: Homework Assignment 10 Question 19, 8.3.35-T Part 4 of 8 HW Score: 75.94%, 151.89 of 200 points Points: 1,55 of 10 Save To investigate if the resparse rate is higher in telephone surveys for interviewers who state'l am not selling anything at the outset of the cal researchers used a sample of 27 different telephone surveys. In each survey, about half of the people were contacted by interviewers using the 'l arratseling anything" introduction and the other half by interviewers using the standard (no mention of "not selling) intraduction. The summary statistics for the response rates are shown to "Not selling" Standardo the right. Complete Introduction Introduction parts a through d Number of Surveys 27 27 below Mean Response Rate 0.264 0.244 Standard Deviation 0.13 0.12 a. Explain why the data should be analyzed as a paired difference experiment. Choose the correct answer bekw. A. The samples are independent. B. The data were collected as paired diferences. Response rates were observed twice from each survey C. A paired diarnos experimentis easier to conduct OD. Comparing paired difference le used when the sample is random. b. Analyze the data in the table using the independent samples t-test. Do you delect a significant difference between the mean response rates of the two methods using -0.057 (Note: It has been established that the paired difference test is the correct test for the data. The independent samples last will be used as a comparison.) Let population 1 be the interviewers using the 'I am not scling anything introduction and population 2 be the interviucrs using the standard introduction.
