In January of 2006, your family moved to a tropical climate. For the year that followed, you recorded the number of rainy days that occurred each month. Your data contained 14, 14, 10, 12, 11, 13, 11, 11, 14, 10, 13, 8. Find the mean, mode, median and range for your data set of rainy days.

A normal distribution has a mean of 16 and a standard deviation of 6. What is the Z score that corresponds with 25?

For the following exercises, solve each system by substitution.
