1. Suppose a population of scores x is
normally distributed
with 𝜇 = 14 and 𝜎 = 5. Use
the standard normal distribution to find the probability indicated.
(Round your answer to four decimal places.)
Pr(10.25 ≤ x ≤ 14)
2. Suppose a population of scores x is
normally distributed
with 𝜇 = 130 and 𝜎 = 10. Use the
standard normal distribution to find the probability indicated.
(Round your answer to four decimal places.)
Pr(x < 140)
3. A quart of milk contains a mean of 22 g of
butterfat, with a standard deviation of 4 g. If the
butterfat is normally distributed, find the probability that a
quart of this brand of milk chosen at random will contain the
following. (Round your answers to four decimal places.)
(a) between 22 and 30 g of butterfat

(b) between 20 and 22 g of butterfat
