(c) Two standard normal curves are shown below, one for the confidence interval calculated in part (a) and one for the significance test conducted in part (b).

(i) For the confidence interval curve, label the critical values for the95%

confidence level and shade the area that represents values in the outer5%

.

(ii) For the significance test curve, label the critical value for the5%

significance level and shade the area representing the values ofz

that would lead to a rejection of the null hypothesis in part (b).
