1. Look at the following phStat output for hypothesis test. What is the conclusion for this t-test for the hypothesis of the mean (sigma unknown)? Should you accept or reject the null hypothesis? Why? 1 tTest for Hypothesis of the Mean 3.

Type II error is known as the consumer's risk because, when it occurs in quality control settings, the customer is getting a product from a process that is not performing properly. Is this a true or false statement? Explain.
