Q. A SRS of 16 seniors from a large metropolitan area school district had a mean Math SAT score of 500 and a standard deviation of s = 100. Assume the population of Math SAT scores for seniors in the district is approximately normally distributed. We wish to calculate a 90% confidence interval for the mean Math SAT score mu for the population of seniors.
Using the above data, illustrate what is the desired 90% confidence interval?
