QUESTION 13 A sample of 16 cookies is taken to test the claim that each cookie contains at least 9 chocolate chips. The average number of chocolate chips per cookie in the sample was 7.875. The standard deviation of the population is 2. Assume the distribution of the population is normal. Let u denote the average number of chocolate chips in all the cookies. The hypothesis to test the claim is: H: 129 Hu<9 The p-value for the test statistics...
