Run complete Hypothesis Tests. Be sure to clearly show all 5 steps, showing all work & pictures. Remember to use the z-distribution, not the t-distribution as described in the book.

1. Are students getting enough sleep? It is recommended that adults (including students) get at least 8 hours of sleep each night. In a sample of 32 students, it was found that they averaged 7.2 hours of sleep with a standard deviation of 1.7 hours. Is this evidence that students are not getting enough sleep? (In other words, is there evidence that the amount of sleep they are getting is less than the recommended 8?)
