Question 7

The total number of pages in college textbooks has been found to be a normal shaped distribution with a mean of µ = 325 pages in length, and a standard deviation = 115. . Find the percentage of books that are between 300 and 400 pages in length. Round to the nearest hundredths place if a fraction. [Note, if your calculated value is not identical to one of the values below, but within plus or minus 0.25 of an answer below, assume it’s a rounding error and select the answer that is closest to your calculated value.]

A. 8.71

Assume that this distribution is normal in shape and the standard deviation = 25. Find the percentage of females who are equal to or below a weight of 110 pounds. Your answer will be the percentile rank, really, of X = 110. Round to the nearest hundredths place if a fraction. [Note, if your calculated value is not identical to one of the values below, but within plus or minus 0.25 of an answer below, assume it’s a rounding error and select the answer that is closest to your calculated value.]
