Suppose that babies' weights at birth are normally distributed with a mean of 7 pounds and a variance of 1 pound. A particular obstetrician is suspected of giving pregnant women poor advice on diet, which would cause babies to be 1 pound lighter on average (but still have the same variance). You observe the weight of n = 10 babies that he delivers. The mean weight of the 10 babies is 6.2 pounds. a) Suppose you want to do a test of the null hypothesis that the obstetrician is not giving poor advice against the alternative hypothesis that he is. Write down the null hypothesis and alternative hypothesis mathematically. b) Perform a 5% test of the null hypothesis. c) What is the power of the test in part (b) ?
