- Assume that we want to construct a confidence interval. Do one of the following, as appropriate: (a) find the critical value ta/2. (b) find the critical value za/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=D156, x 29.3 hg, s = 7.7 hg. The confidence level is 90%.Construct the indicated confidence interval for the population mean u using the t-distribution. Assume the population is normally distributed. c= 0.90, x= 13.6, s=3.0, n= 10 (Round to one decimal place as needed.)With a large sample (N>30), the Excel function CONFIDENCE.T is used to calculate the confidence interval.
