Isabel attends a fashion institute that has no on-campus housing. The distance she commutes between her home and the campus is 19 kilometers. The mean distance commuted to campus among all students at the fashion institute is 15 kilometers with a standard deviation of 6 kilometers. (a) Find the -score of Isabel's commute distance relative to the commute distances among all the students at the institute. Round your answer to two decimal places. == (b) Fill in the blanks to interpret the-score of Isabel's commute distance. Make sure to express your answer in terms of a positive number of standard deviations.

Let's consider the annual precipitation levels in Los Angeles county. Suppose the average annual precipitation in LA county is normally distributed with a mean of 15 inches and a standard deviation of 3 inches. We can classify the precipitation levels in the following way: Dry Annual precipitation is more than 1 standard deviation below the mean. Normal Annual precipitation is less than 1 standard deviations below the mean and less than 2 standard deviation above the mean. Humid Annual precipitation is more than 2 standard deviations above the mean. Before answering the following questions it may be helpful to mark on a bell shaped curve where the above regions lie. According to the empirical rule, what is the probability of experiencing a Dry year in Los Angeles?
