0 pts A large Midwestern university is interested in estimating the mean time that students spend at the student recreation center per week. A previous study indicated that the standard deviation in time is about 25 minutes per week. If the officials wish to estimate the mean time within ± 4 minutes with a 90 percent confidence, what should the sample size be? 106 Can't be determined without the sample mean. 105 105.685

Question 3 A researcher wants to test if the elementary school children spend less than 30 minutes per day on homework. A random sample of 64 children from the school shows that they spend an average of 24.5 minutes per day on homework. Assume that the standard deviation = 15.3 minutes, and that the test is to be made at the 1% significance level. What is the critical value? -2.06 -2.33 -2.58 -1.96

A claim is made that college students spend an average of 20 hours per week studying for their courses. You believe the true population average is different than 20 hours, and you would like to test the null hypothesis that μ = 20 hours versus the alternative hypothesis that μ ≠ 20 hours. You gather data from a random sample of 100 college students and calculate a test statistic of 1.2. This means the p-value would be what? A 0.0576...
Mark wants to estimate the mean length of time (in minutes) all Middle School students spend reading online books. To determine this estimate, he took a random sample of 15 people and obtained the following results: 40, 110, 56, 20, 15, 10, 82, 60, 90, 11

The School Nutrition Association wants to study the average number of calories in home-packed lunches for elementary students. Specifically, they want to know if home-packed lunches have significantly more calories than the recommended 600 calories needed for daily energy and health. In a sample of 25 home-packed lunches, the average number of calories was 615 calories with a standard deviation of 30 calories. Use the appropriate analysis to determine if the average home-packed lunch is greater than 600 calories. Identify...
