A. X ~ N(66, 6.25)
b.


Using a standard normal probability table to find probability values for the z-scores, we get:
P(65 < X < 69) = 0.1554 + 0.3849 = 0.5403
c. z= 0.524 and -0.524

1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4
Add 4/10 to 9/10.
9/10 + 4/10 = 13/10
Simplify 13/10 into a mixed number by subtracting 10 from the numerator and turning it into a whole.
13/10 ⇒ 1 3/10
