H0:μ≥150Ha:μ<150p-value = 0.0622 alpha = 0.01 Do not reject the null hypothesis. At the 1% significance level, there is not enough evidence to conclude that freshmen students study less than 2.5 hours per day, on average. The student academic group’s claim appears to be correct.

Type II error: We conclude that the proportion of high school seniors who get drunk each month is 29% when, in fact, it is not 29%. Type I error: We conclude that fewer than 5% of adults ride the bus to work in Los Angeles, when the percentage that do is really 5% or more.
