e Exercise 9 (12 POINTS) An important aspect of a federal economic plan was that consumers would save a substantial portion of the money that they received from an income tax reduction. Suppose that early estimates of the portion of total tax saved, based on a random sampling of 35 economists, had a mean of 26% and a standard deviation of 12%. a. What is the approximate probability that a sample mean estimate, based on a ran- dom sample of n = 35 economists, will lie within 1% of the mean of the population of the estimates of all economists? b. Is it necessarily true that the mean of the population of estimates of all economists is equal to the percent tax saving that will be achieved
