We are given that the distribution of heights of women is a bell shaped distribution that is a normal distribution.
Men:
Mean, μ = 69.4 inches
Standard Deviation, σ = 3.0 inches
We are given that the distribution of heights of men is a bell shaped distribution that is a normal distribution.
Formula:

Hope that was helpful, please let me know if you have any questions.
The first thing we must do in this case is to solve both inequations.
We have then:
Inequality 1:
6 -2x <12
6-12 <2x
-6 <2x
-6/2 <x
-3 <x
Inequality 2:
7 + 2x <-11
2x <-11-7
2x <-18
x <-18/2
x <-9
Answer:
(-inf, -9) U (-3, inf)
