Assume that we want to construct a confidence interval. Do one of thefollowing, asappropriate: (a) find the critical value t Subscript alpha divided by 2

t/2, (b) find the critical value z Subscript alpha divided by 2

z/2, or(c) state that neither the normal distribution nor the t distribution applies.

The confidence level is 99

99%, sigma
