Average hours per week listening to the radio. The Student Monitor surveys 1200 undergraduates from four-year colleges and universities throughout the United States semiannually to understand trends among college students.12 Recently, the Student Monitor reported that the average amount of time listening to the radio per week was 11.5 hours. Of the 1200 students surveyed, 83% said that they listened to the radio, so this collection of listening times has around 204 (17% × 1200) zeros. Assume that the standard...

A study reports that recent college graduates from New Hampshire face the highest average debt of $31,630 (The Boston Globe, May 27, 2012). A researcher from Connecticut wants to determine how recent undergraduates from that state fare. He collects data on debt from 40 recent undergraduates. A portion of the data is shown in the accompanying table. Assume that the population standard deviation is $5,000. Debt Debt 24,045 23,911 19,150 24,036 26,756 19,159 31,924 26,764 31,529 31,921 34,211 31,531 14,622...

Student Debt – Vermont: The average student loan debt of a U.S. college student at the end of 4 years of college is estimated to be about $22,600. You take a random sample of 136 college students in the state of Vermont and find the mean debt is $23,500 with a standard deviation of $2,200. We want to construct a 90% confidence interval for the mean debt for all Vermont college students. (a) What is the point estimate for the...
