## [answered] A group of statistics students decided to conduct a survey

A group of statistics students decided to conduct a survey at their university to find the average (mean) amount of time students spend studying per week. Based on a simple random sample, they surveyed 65 students. The survey showed that students studied an average of 20 hours per week with a standard deviation of 7 hours.

A national study found that students studied, on average, 19.5 hours. You hypothesize that students at this university study more than the national average.

Using a 95% confidence level (alpha = 0.05), what is the probability of a Type I error?
