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 90%, o = 22.2, and the histogram of right-eye vision measurements from a random sample of 63 adult males is shown to the right. Frequency Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. Za/2= (Round to two decimal places as needed.) OB. ta/2= (Round to two decimal places as needed.) OC. Neither the normal nor the t distribution applies.

4. Please answer the following probability question.
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 tx/2, or (c) state that neither the normal nor the t distribution applies. Confidence level is 90%, o = 22.2, and the histogram of right-eye vision measurements from a random sample of 63 adult males is shown to the right. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. OA. Zα/2= (Round to two decimal places as needed.) ta/2= (Round to two decimal places as needed.) C. Neither the normal nor the t distribution applies. Frequency B. 50- 40- 30- 20- 10- 50 100 150 200 Vision in Right Eye
