A scientist has read that the mean birth weight, µ, of babies born at full term is 7.3 pounds. The scientist, believing that u is different from this value, plans to perform a statistical test. She selects a random sample of birth weights of babies born at full term and finds the mean of the sample to be 7.7 pounds and the standard deviation to be 1.5 pounds. Based on this information, answer the questions below. What are the null hypothesis (H,) and the alternative hypothesis (H,) that should be used for the test? H: u is ? H: u is (7 In the context of this test, what is a Type I error? A Type I error is ? the hypothesis that u is ? when, in fact, u is ? Suppose that the scientist decides to reject the null hypothesis. What sort of error might she be making?
