Facial prototyping 1.5.19 Reconsider Exploration 1.3, where we explored whether the long-run proportion that students in a class would correctly assign the names Bob and Tim to the pictures. We tested to see if this long-run proportion is more than 0.50. a. State the appropriate null and alternative hypotheses in the context of this study. b. In a class of one of the authors 19 out of 30 students correctly identified that the face on the left belonged to Tim. Using an appropriate applet, find the p-value using a one-proportion zz-test (theory-based/normal approximation). c. Summarize your conclusion from your p-value. d. What is the zz-statistic for the test
