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. 10 The middle interval that captures 95% of the means from sample of size ? = 92 is, a 492.84 544.48 b 488.54 548.78 c 484.23 553.09 d 479.93 557.39

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.

The middle interval that captures 95% of the means from sample of size ? = 92 is,
