Let
Z
be a standard normal random variable. Use the calculator
provided, or this table, to determine the value of c.
P(c ≤ Z≤ −0.79) = 0.1826
Carry your intermediate computations to at least four decimal
places. Round your answer to two decimal places.
According to her doctor, Mrs. Brooks's cholesterol level is
higher than only 15% of the females aged 50 and
over. The cholesterol levels among females aged 50 and
over areapproximately normally distributed with a mean
of 225mgdLand a standard deviation of 30mgdL. What
is Mrs. Brooks's cholesterol level? Carry your intermediate
computations to at least four decimal places. Round your answer to
one decimal place.
