A college claims that its recent graduates have an average annual income of $43,725. You randomly sample on 27 of the college’s graduates and an average income of $38,251 with a standard deviation of $7,856. Determine if the income of the graduates is significantly less than the income claimed by the college using α = 0.01 and the prob-value approach. (show bell shape graph)

The dean of students of a large private college claims that the average distance commuting students travel to the campus is 32 miles. The commuting students feel otherwise. A sample of 64 students was randomly selected and yielded a mean of 35 miles and a standard deviation of 5 miles. Identify the null and alternative hypotheses. Test the dean’s claim at the 5 percent level of significance (α = 0.05) using critical approach and state a conclusion.    (Hint: two-tailed test,...

A small college with 300 students claims that its students have an average IQ of 100. A sample of 9 of the 30 students in the intermediate statistics class had an average of 110 with a calculated standard deviation of 12. IQ tests, like most standardized tests, are designed so that the distribution of scores is approximately normal. Using a level of significance of 0.01, is there any evidence that the students in this class are any dumber or smarter...

In a recent study, researchers found that Americans spent an average of 5.1 hours on leisure per day (306 minutes). You expect that nurses spend significantly less time per day on leisure than the national average. You find in a sample of 43 nurses, the average number of hours of leisure per day was 255 minutes with a standard deviation of 60 minutes. Use the critical-value approach for a t-test (where α = .01) to determine if there is a...
