AT&T Wireless store. Lisa has been signing up an average of 63
new cell phone customers every month with a standard deviation of
21, while Brad signs up an average of 72 new customers with a
standard deviation of 13. The store manager offers both Lisa and
Brad a $90 incentive bonus if they can sign up more than 90 new
customers in a month. Assume a normal distribution to answer the
following questions. [You may find it useful to reference
the z table.]
a. What is the probability that Lisa will earn the $90
incentive bonus? (Round "z" value to 2 decimal
places and final answer to 4 decimal places.)
b. What is the probability that Brad will earn the $90 incentive bonus? (Round "z" value to 2 decimal places and final answer to 4 decimal places.)
