Suppose a researcher is testing someone to see whether she or he can tell Soda X from Soda Y, and the researcher is using 34trials, half with Soda X and half with Soda Y. The null hypothesis is that the person is guessing. a. About how many should the researcher expect the person to get right under the null hypothesis that the person is guessing? b. Suppose person A gets 32 right out of 34, and person B gets 20 right out of 34. Which will have a smaller p-value, and why?
