1. A local hardware store has a "Savings Wheel" atthe checkout. Customers get to spin the wheel and,when the wheel stops, a pointer indicates how muchthey will save. The wheel can stop in any one of50 sections. Of the sections, 10 produce 0% off,20 sections are for 10% off, 10 sections for 20%,5 for 30%, 3 for 40%, 1 for 50%, and 1 for 100%off. Assuming that all 50 sections are equally likely,

a. What is the probability that a customer's purchasewill be free (100% off)?

b. What is the probability that a customer will get nosavings from the wheel (0% off)?

c. What is the probability that a customer will get atleast 20% off?

2.For the following z scores, determinewhether the tail is on the right or left side of the lineand find the proportion in the tail.

a. z =2.00

b. z =0.60

c. z =-1.30

d. z =-0.30

3. In class, we have been learning about z-scores. What population would be interested in better understanding how you or another individual compares to the average? For example, I was interested in how far below the average I am in height regarding z-score. I was also interested in the heights of baseball players.
