Astudent wants to estimate the mean score of all college students for a particular exam.
first use the range rule of thumb to make a rough estimate of the standard deviation of those scores. possible scores range from 0 to 1600
use the ti-83/84 and the estimated standard deviation to determine the sample size corresponding to a 95​% confidence level and a margin of error of 100 points.
a confidence level of 95​% requires a mimimum sample size ​(round up to the nearest​ integer.)
