Chapter 6 Assignment The Environmental Protection Agency (EPA) fuel economy estimates for automobile models tested recently predicted a mean of 30.8 miles per gallon, with a standard deviation of 4.1 miles per gallon. Assume that a Normal model applies. Find the probability that a randomly selected automobile will average: 1. Less than 28 miles per gallon. 2. More than 26 miles per gallon. 3. Between 27 and 33 miles per gallon.

On this page, do the assignment from the textbook called 6.3 Normal Distribution (Lap Times). You may have to look at the ONLINE version of the test to find it. Note that the “empirical data” is to use your list of 36 times to find percentiles, etc. Do not use mean and SD for that. The “theoretical model” is using the mean and standard deviation to find percentiles, etc.
