e 1: Question 17 (5 points) 2A3 Following are the weights of 5 boxes of cookies, each of which is labeled as containing 16 ounces. Assume that the population of weights is normally distributed. 15.91, 14.46,1488, 16.07, 14.79 A quality control inspector wants to know whether the mean weight is actually less than 16 46,14.88, 16.07, 14.79 ounces. Compute the Pvalue of the test. Write down your P-value. You will need it for the next question. Write only a number...

15. Cookies: Following are the weights of 8 boxes of cookies, each of which is labeled as containing 16 ounces. Assume that the population of weights is normally distributed. 15.91 16.06 16.08 15.97 16.02 15.88 15.89 16.01 Can you conclude that the population standard deviation is less than 0.1? Use the α = 0.01 level of significance.

2. Boxes of sugar are filled by machine with considerable accuracy. The distribution of box weights is normal and has a mean of 32 ounces with a standard deviation of 2 ounces. A quality control inspector takes a sample of n=16 boxes and finds that the sample mean is 31 ounces of sugar. What is the probability of obtaining such a sample with this much shortchanging in its boxes? Should the inspector suspect that the filling machinery needs repair?

Question 4 (1.25 points) Soda cans of a certain kind are labeled as containing 12 ounces. A quality control inspector believes that the mean weight may be more than this, so she performs a hypothesis test of Ho: mean = 12 versus Hy: mean > 12. She does not reject the null hypothesis. Which of the following is an appropriate conclusion? " There is not enough evidence to conclude that the mean weight of the soda in the cans is...

Question 8 (7 points) In a study to determine whether counseling could help people lose weight, a sample of people experienced a group-based behavioral intervention, which involved weekly meetings with a trained interventionist for a period of six months. The following data are the numbers of pounds lost for 5 people 18.2, 3.9, 17.1, 8.8, 13.0 It is reasonable to assume that the population is approximately normal. A researcher wants to know whether the mean weight loss is greater than...
