Question 1150855
<font face="times" color="black" size="3">
The sample size n = 240 satisfies the inequality n > 30. 


So the distribution of sample variances will be approximately normal according to the Central Limit Theorem (CLT). This theorem says that whenever n > 30, then the distribution of sample means, sample variances, etc will be approximately normal. This is handy when doing things like finding areas under the curve to determine P values.

side note: I honestly don't know what the tutor @MathLover1 is referring to when they wrote "would have to make it a good 80 by 90 by 80 by 90 by 80 which would be 4+4 and make that 69". It's possible they mixed up two problems together.
