Step-by-step explanation:
Find the z-scores for the two scores in the given interval.

For the score x =391,

.
For the score x = 486,

Now you want the area (proportion of data) under the normal distribution from z = -1 to z = 0. The Empirical Rule says that 68% of the data falls between z = -1 to z = 1. But the curve is symmetrical around the vertical axis at z = 0, so the answer you want is HALF of 68%.
Hey there! :D
So, we want to multiply that by 2. The table represents one year at Weatherford College.
8,965*2= 17,930
I heard the question mention 'reasonable'. It also said 'meet the cost'. So I would assume that 17,930 meets most of the cost. I think that's what it wanted to have. A couple thousand dollars may be reasonable, but will it meet the cost? Probably not.
I would say "A" is the best answer.
I hope this helps!
