2. A series of studies are done with the following associated p-values. Study A: Study B: Study C: Study D: Study E: P-Value = 0.03 P-Value = 0.0002 P-Value = 0.01 P-Value = 0.009 P-Value = 0.851 a. If a = 0.02, which studies are statistically significant? b. If a = 0.01, which studies are statistically significant? c. Which study is the most statistically significant? d. If a = 0.01, what is the probability of a false positive (type | error)? e. Which study's p-value is probably a sign that there was an error in the setup? 3. The following shows three shaded t-distributions. The shaded areas represent probabil Which of these three sketches cannot represent a P-value? Explain. a. b. C . -Ito Itol to to
