Question: 1. (c) Imagine you planned to increase your sample size to n = 64 (instead of 16). Compute the new standard error. Then re- sketch

1. (c) Imagine you planned to increase your sample size to n = 64 (instead of 16). Compute the new standard error. Then re- sketch the null and alternative. This will again be a picture of two sampling distributions that overlap. Use the steps discussed in class: (i) draw the null, (ii) label the critical regions, (uil) draw the alternative, and (iv) find the area of the alternative that crosses into the critical region of the null, and shade that area. USE COLOR PENCILS. 50 1. (d) Examine your sketch above. 1. What is your approximate power now (this is the shaded area)? fi. What is your approximate Type II error rate now? ili. What is your Type I error rate now? 1. (e) Examine how your answers changed from #1(b) to #1(d). When the sample size increased, what happened to: 1. Power? (increase, decrease, or no change) increase i. Type II error rate? (increase, decrease, or no change) decrease iii. Type I error rate? (increase, decrease, or no change) no change
