Extracted text: A scientist has read that the mean birth weight of babies born at full term is 7.6 pounds. The scientist has good reason to believe that the mean birth weight of babies born at full term, µ, is greater than this value and plans to perform a statistical test. She selects a random sample of 100 birth weights of babies born at full term. Suppose that the population of birth weights of babies born at full term has a standard deviation of 1.6 pounds and that the scientist performs her hypothesis test using the 0.10 level of significance. Based on this information, answer the questions below. Carry your intermediate computations to four or more decimal places, and round your responses as indicated. (If necessary, consult a list of formulas.) (a) What are the null hypothesis H, and the alternative hypothesis H, that the scientist should use for the test? 合 H: I (b) What is the probability that the scientist rejects the null hypothesis when, in fact, D=D
