According to a research study, college students spent 19.7 hours doing homework per week last year, on average. A random sample of 21 college students was surveyed and the mean amount of time per week each college student spent on homework was 19.1. This data has a sample standard deviation of 1.9. (Assume that the scores are normally distributed.) Researchers conduct a one-mean hypothesis test at the 10% significance level, to test if the mean amount of time college students spend on homework per week is less than the mean amount of time last year.
