Question 9: If we run 100 hypothesis tests at the same time on null hypotheses that are all true, the average number of null hypotheses that we would reject at the 5% test level is 5. (TRUE/FALSE) Answer: Question 10: The t-value for a two-sided 95% confidence interval is smaller than the t-value for a two-sided 99% confidence interval for any sample size greater than 1. (TRUE/FALSE) Answer: Question11: If variable X comes from a Binomial distribution B(n,p), and variable Y comes from a Binomial distribution B(n, 1-p), the variance of X and Y are the same. (TRUE/FALSE)
