Answer:
a) 0.383
b) 0.375
Step-by-step explanation:
a) Calculate each z-score.
z = (x − μ) / σ
z₁ = (112 − 118) / 12 = -0.5
z₂ = (124 − 118) / 12 = 0.5
Use a calculator or z-score table to find the probability.
P(-0.5 < Z < 0.5) = 0.6915 − 0.3085 = 0.383
b) 0.383 × 16 ≈ 6. So the expected proportion would be 6/16 = 0.375.

Answer =
E = 1/2 = 0.500
__________________________________________________
Now you need to rearrange the problem ( common sense :) :
1/2 * e - (1/4 ) = 0 | Now we need to Simplify 1/4 : 1/2 * e - 1/4 = 0

Now we need to simplify 1/2 : 1/2 * e - 1/4 = 0

What are there denominators??? = 2 and 4 ,,,,,, DUH . LOL
The lease common multiple is 4.
Now divide 1/2 by e which is 1/2 = 0.500
i hope this helps you a lot
