To construct a confidence interval using the given confidence level, do whichever of the following is appropriate. (a) Find the critical value z/2, (b) find the critical value t/2, or (c) state that neither the normal nor the t distribution applies. 99%; n= 200; o is unknown; population appears to be skewed Click here to view a table of critical t-values. Click here to view page 1 of the standard normal table. Click here to view page 2 of the standard normal table. Choose the correct answer below. O A. Z/2 = 2.575 O B. ta/2 = 1.972 Oc. ta/2 = 2.601 O D. Za/2 = 1.645 O E. Neither the normal nor the t distribution applies.
