A simple random sample of size n is drawn from a population that is normally distributed. The sample mean, x̅, is found to be 107 , and the sample standard deviation, s, is found to be 10 .
(a) Construct a 98 % confidence interval about μ if the sample size, n, is 22 .
(b) Construct a 98 % confidence interval about μ if the sample size, n, is 12 .
(c) Construct a 95 % confidence interval about μ if the sample size, n, is 22 .
(d) Could we have computed the confidence intervals in parts (a)-(c) if the population had not been normally distributed?
(a) Construct a 98 % confidence interval about μ if the sample size, n, is 22 .
