2) Refer to the last problem. Consider repeating the task offinding similar confidence intervals 4000 times (each of these 4000intervals has the same confidence level of 99% and each interval isbased on the same sample size eleven). Approximately how many ofthese intervals do you expect to include the true forearm length ofall men? (Your answer must be given as an integer.
