A variable is normally distributed with mean
15
and standard deviation
3.
a. Determine the quartiles of the variable.
b. Obtain and interpret the
90th
percentile.
c. Find the value that​ 65% of all possible values of the
variable exceed.
d.
Find the two values that divide the area under the corresponding
normal curve into a
middle area of 0.95 and two outside areas of 0.025. Interpret
the answer.
