1. Gas Mileage The Environmental Protection Agency (EPA) routinely collects data concerning automobile gas mileage. Suppose the EPA wanted to be 90% confident of its estimate for the mean fuel economy rating for a certain manufacturer's entire line of passenger cars (n = 10). Here is what they found: First they found the Then they determined the Next, they found the interval endpoints. Finally, they formed the interval estimate: mean of a margin of error: random sample: E= 3.0 Left: 31.1 - 3.0 = 28.1 A 28.1 < u < 34.1 *= 31.1 Right: 31.1 + 3.0 = 34.1 + 27 29 30 31 32 33 35 Given all of this information, determine the standard deviation of the original sample. 介
