(Due to Corona virus I have had to do online for the rest of the semester, I am really struggling in my Statistics 200 course.)
(Ch 7 Sampling Distribution of Sample Mean) (It uses a chart table but I have no idea which table...)
For the nation’s high school seniors, being accepted to the college of their choice may not present as much of a problem as paying the tuition. Assume that the distribution of yearly tuition for 4-year accredited colleges has a mean of $25,000 and a standard deviation of $5,000. A senior randomly selects thirty-six colleges and requests information concerning their yearly tuition costs. Find the probability that the average yearly tuition of thirty-six selected colleges is between $21,000 and$32,000.
