To construct a confidence interval using the given confidencelevel, do whichever of the following is appropriate. (a) find the critical value z subscript alpha divided by zα/2, (b) find the critical value t subscript alpha divided by tα/2, or (c) state that neither the normal nor the t distribution applies.? 95 % ; n=100; σ = unknown; population appears to be skewedchoose the correct answer below. a. tα/2 =2.626b. zα/2 = 1.96c. tα/2 =1.984d. zα/2 = 2.575e. neither the normal nor the t distribution applies
