Random samples of female and male UVA undergraduates are asked to estimate the number of alcoholic drinks that each consumes on a typical weekend. The data is below: Females (Population 1): 4, 4, 0, 0, 0, 0, 1, 4, 1, 0 Males (Population 2): 4, 4, 4, 6, 6, 3, 6, 4, 5, 4 Give a 97.5% confidence interval for the difference between mean female and male drink consumption. (Assume that the population variances are equal.) Confidence Interval =

During the nutrition research, the amount of consumed kilocalories per day was measured for 18 people - 10 women and 8 men. Results are as follows: Women: 1967, 1666, 1607, 1622, 1749, 1805, 1590, 1921, 1822, 1675; Men: 2076, 2071, 2167, 1885, 1841, 1868, 2299, 2119. Calculate a 90% confidence interval on the mean for women and men separately. Assume distribution to be normal. Round your answers to the nearest integer (e.g. 9876). Women: i

Students at a local elementary school were randomly selected to participate in a reading fluency program. The program is designed to increase their reading fluency. A total of 17 students each took a pretest before the program and posttest after the program. The mean differences in the posttest and pretest is 11. The administration decided that all students in the school would participate in the program next school year. Let µD denote the mean difference in the student scores. The 90 percent confidence interval estimate of the mean difference for all students is (7, 15). What is an appropriate interpretation of the confidence interval? O For any µD ≥ 10, the sample result is quite likely. O μD is positive, with a probability of 0.90. O μD is negative, with a probability of 0.90. O HD is between 7 and 15. O For any up with 7 < µp < 15, the sample result is quite likely.

A certain test preparation course is designed to help students improve their scores on the GMAT exam. A mock exam is given at the beginning and end of the course to determine the effectiveness of the course. The following measurements are the net change in 3 students' scores on the exam after completing the course: 17,20,26Using these data, construct a 95% confidence interval for the average net change in a student's score after completing the course. Assume the population is approximately normal. Step 1 of 4 : Calculate the sample mean for the given sample data. Round your answer to one decimal place.

A survey of credit card holders revealed that Americans carried an average credit card balance of $3900 in 1995 and $3300 in 1994 (U.S. News & World Report, January 1, 1996). Suppose that these averages are based on random samples of 400 credit card holders in 1995 and 450 credit card holders in 1994 and that the population standard deviations of the balances were $880 in 1995 and $810 in 1994.
