Question

Homework Problem 9.13 (v5) or NONE (v7) Do students at your school study more, less, or about the same as at other business schools? Business Week reported that at the top 50 business schools, students studied an average of 14.6 hours. Set up a hypothesis test to try to prove that the mean number of hours studied at your school is different from the 14.6 hour benchmark reported by Business Week a) Write Step 1. Include the Null and Alternative Hypothesis, the statements and actions. b) What is a Type I Error FOR YOUR TEST? Be specific. c) What is a Type II Error FOR YOUR TEST? Be specific.

Explanation / Answer

Answer to the question is as follows:

a.So, the claim to be test' given in the question:

Ho: Mu = 14.6 hours
Ha: Mu != 14.6 hours

b. Type 1 error the incorrect rejection of a true null hypothesis (also known as a "false positive" finding). Specficially for us in the question it is:

Incorrect rejection of the hypothesis when actually we know that the average number of hours studied at school is equal to 14.6

c.Meanwhile a type II error is incorrectly retaining a false null hypothesis (also known as a "false negative" finding). So, we make a type II error when we incorrectly conclude that the average number of hours studied at school is equal to 14.6 when actually that' not the case.
