Problem 48E

The following graph portrays the distribution of the number of Biggie-sized soft drinks sold at a nearby Wendy's for the last 141 days. The mean number of drinks sold per day is 91.9 and the standard deviation is 4.67.

If we use the Empirical Rule, sales will be between what two values on 68 percent of the days? Sales will be between what two values on 95 percent of the days?

Solution:

Step 1 of 3:

The graph of the distribution of the number of Biggie- sized soft drinks for the last 141 days is given.

The mean number of drinks sold per days is 91.9 and the standard deviation is 4.67.

By using Empirical rule, we have to find the sales will be between what two values on 68 percent of the days. And sales will be between what two values on 95 percent of the days.
