A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x, is found to be 17.1, and the sample standard deviation, s, is found to be 5.8. (a) Construct a 96% confidence interval about if the sample size, n, is 38. (b) Construct a 96% confidence interval about if the sample size, n, is 55. How does increasing the sample size affect the margin of error, E? (c) Construct a 98% confidence interval about if the sample size, n, is 38. How does increasing the level of confidence affect the size of the margin of error, E? (d) If the sample size is 23, what conditions must be satisfied to compute the confidence interval?

(a) Construct a 96% eonfidence intervet about it the sample size, n, is 38 (b) Construct a 96% confidence interval about if the sample sce, n, is 55 . How does increasing the sample vize affect the margin of error, E? (e) Construct a 96% confidence inserval about if if the sample wae, n, is 34 . How dees increasing the ievel of confldence affect the size of the margin of error, E ? (d) if the sample size is 23 , what conditions must be satisfied to compule the confidence interval
