Compute the critical value z Subscript alpha divided by 2 that corresponds to a 89% level of confidence. z Subscript alpha divided by 2equals nothing (Round to two decimal places as needed.)
At 89% confidence level the z is ,
= 1 - 89% = 1 - 0.89 = 0.11
/ 2 = 0.11 / 2 = 0.055
Z/2 = Z0.055 = 1.60
= 1.60
critical value z = 1.60
