Step 1
The normal distributions are bell-shaped. Therefore the empirical rule can be stated as below:
Step 2
For the bell-shaped distributed variable,
The observations that lie within 11 standard deviation from the mean is around 68.26%.
The observations that lie within 22 standard deviations from the mean is around 95.44%.
The observations that lie within 33 standard deviations from the mean is around 99.74%.

The manager of the store in the preceding exercise calculated the residual for each point in the scatterplot and made a dotplot of the residuals.
The distribution of residuals is roughly Normal with a mean of $0 and standard deviation of $22.92.
The middle 95% of residuals should be between which two values? Use this information to give an interval of plausible values for the weekly sales revenue if 5 linear feet are allocated to the stores

At a certain college, 6% of all students come from outside the United States. Incoming students there are assigned at random to freshman dorms, where students live in residential clusters of 40 freshmen sharing a common lounge area. How many international students would you expect to find in a typical cluster? With what standard deviation?
