I'm not sure if that's the correct method of finding that (it could be, I was just never shown that kind of method). What I did was multiply everything out, that way you have two numbers vs two equations. Then add those two numbers and turn that into scientific notation.

According to a study by de Anna students, the height for Asian adult males is normally distributed with an average of 66 inches
Maslowich
A. X ~ N(66, 6.25)

b.z_{1} =\frac{65-66}{2.5}=-0.4
z_{2} =\frac{69-66}{2.5}=1.2
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
0.524=\frac{X-66}{2.5}
1.31 = X - 66
X = 67.31
When z = -0.524, X = 64.69.
P(64.69 < X < 67.31) = 0.4
