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 tα/2; or (c) state that neither the normal nor the t distribution applies. Confidence level is 99%; n=10; σ is not known; and the normal quantile plot of measured right-ear hearing thresholds from 10 randomly selected adult females is shown to the right. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. A. zα/2=enter your response here (Round to two decimal places as needed.) B. tα/2=enter your response here (Round to two decimal places as needed.) C. Neither the normal nor the t distribution applies.
