Washington’s National Zoo reports that visitors spend an average of 2.4 hours per visit. A worker at the zoo disagrees and thinks that the average time spent is not 2.4. He surveyed 15 randomly selected zoo visitors, and found that in this sample the average time spent was 2.1 hours with a standard deviation of 0.6 hours.

Do you believe that the zoo worker’s claim is more reasonable than the National Zoo’s? Test the worker’s claim with a significance level of 0.05.
