Expert Solution

An estimated 68% of the data within the set is positioned within one standard deviation of the mean; i.e., 68% lies within the range [M - SD, M + SD].

Approx. 68% of the data lies between ± 1 SD, or between 7391.79 and 8965.03

What are some characteristics of a normal distribution? What does the empirical rule tell you about data spread around the mean? How can this information be used in quality control? Can you compare apples and oranges, or maybe elephants and butterflies? In most cases the answer is no – unless you first standardize your measurements. What are a standard normal distribution and a standard z score?
