Problem 1 {10 points): What factor do you need to decide upon if you have the Power, Sample Size, and Effect Size identified? a) Significance Level (alpha) b) Number ofTreatments c) Variance Problem 2 {10 points): For a chosen alpha = 0.01, what is the probability of a true negative? a) 90% b) 99% c) 99.9% Problem 3 {10 points): When a null hypothesis is rejected, but is true (that there is no difference), what type of error is this? a) Type | b) Type II Problem 4 {10 points): A clinical study's samples were incorrectly processed. Upon reprocessing those samples, it was found that the difference in means increased and variance was unchanged. Given all other factors ofthe study were unchanged, what happened to the statistical power of the study? a) It increased b) It decreased
