The Graduate Management Admissions Test (GMAT) has a mean of 500
and a standard deviation of 100. Using this information,
find the probability for the three scenarios shown
below. (3.5 pts.)
Note: Show your z score rounded to two decimal
places (i.e., 2.85) (Showing calculations may help you
earn partial credit.) Show your probability rounded to four
decimal places (i.e., .6560).
a) What is the probability of a GMAT score less than
548?
b) What is the probability of a GMAT score...

You are asked to do a study of shelters for abused and battered
women to determine the
necessary capacity I your city to provide housing for most of
these women. After recording data
for a whole year, you find that the
mean number
of women in shelters each night is
250
, with a
standard deviation of 75
. Fortunately, the distribution of the number of women in the
shelters
each night is normal, so you can answer the following...
