Crystal Jenkins STA 2023 TR 10:00am Case Study pg 396 1. Complete the hypothesis test for all adults (men and women) by performing the following steps. Use a level of significance of a = 0.05. (a) Sketch the sampling distribution. (b) Determine the critical values and add them to your sketch. (c) Determine the rejection regions and shade them in your sketch. (d) Find the standardized test statistic. Add it to your sketch. (e) Make a decision to reject or fail to reject the null hypothesis.
