Information needed for the next two problems: A bored statistician is interested in researching length of commercial breaks on cable channels (ESPN, TNT, etc.) and comparing them to the length of commercial breaks on the networks (ABC, CBS, NBC, FOX). She times a random sample of commercials from each of the two types of broadcasts which are assumed to be normally distributed. Source n Mean(min.) Std. Dev. (min.) Cable 15 2.36 0.16 Network 12 2.18 0.13 Based on your previous answer for the upper bound and assuming the lower bound ratio of variances of cable to network is 0.5531, your conclusion about the spread of the variances of cable vs network commercials is O 1 is in the interval so statistically the same O O is in the interval so statistically the same O 1 is not in the interval so statistically different O O is in the interval so statistically not the same O 1 is in the interval so statistically not the same

A student who took Stat 2 last semester learns that their overall course score was at the 85th percentile. Assuming that a histogram of all the Stat 2 course scores from last semester follows the normal curve, this means that this student had a score that was how many SDs above the average score?
