We are interested in the population proportion of adult Americans who are worried a lot about the quality of education in our schools. Another question in the poll was “ you worried about the quality of education in our schools?” Sixty-three percent responded “a lot”. Assume the underlying population is normally distributed. The sample mean is 13.30 with a sample standard deviation of 1.55. Use the following information to answer the next two exercises: A quality control specialist for a restaurant chain takes a random sample of size 12 to check the amount of soda served in the 16 oz.
