1. Collected data shows that about 220,000 high schoolers took the AP in 2020. The FRQ section of the exam consisted of five problems. Each FRQ is scored on a o to 4 scale (with 4 being the best). For a certain problem, a random sample of 35 submissions produced a mean score of i =1.627 and a standard deviation of 3, = 1.320. A. Find the standard error of the mean and interpret it. B. Construct a 99% confidence interval to estimate the true mean score on this question and interpret it.
