Assume that we want to construct a confidence interval. Do one of the following, as appropriate. (a) Find the critical value Zα/2, (b) find the critical value to/2, or (c) state that neither the normal nor the t distribution applies. Confidence level is 99%, o is not known, and the histogram of right-eye vision measurements is obtained from a random sample of 9 adult males. Frequency Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. Zα/2 = (Round to two decimal places as needed.) B. ta/2= (Round to two decimal places as needed.) OC. Neither the normal nor the t distribution applies. 10- 0+ 50 100 150 200 Vision in Right Eye
