Here are summary statistics for randomly selected weights of newborn girls: n = 158, x̅=30.2 hg, s = 7.8 hg. The confidence level is 99%
Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value tα/2, (b) find the critical value zα/2 or (c) state that neither the normal distribution nor the t distribution applies.Here are summary statistics for randomly selected weights of newborn girls: n = 158, x̅=30.2 hg, s = 7.8 hg. The confidence level is 99% Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
