Now consider the textbook expense of all IUPUI students. The mean and variance of textbook expense of all IUPUI students are as follows: ? = $518.66 ?² = 15965.14 From the population of IUPUI students you take repeated samples of size ? = 92 and compute the sample mean textbook expense. 11 To obtain a margin of error of ±$20 for the interval that captures 95% of the sample means, the minimum sample size is ________. a 266 b 222 c 185 d 154
