Answer:
The point estimate used to estimate the mean height of all adult males in Idaho is 69.505 inches.
Step-by-step explanation:
Each confidence interval has two bounds, the lower bound and the upper bound. The points estimate used to estimate the mean is the halfway point between those two bounds, that is, the sum of those two bounds divided by two.
In this problem, we have that:
Lower bound: 62.532
Upper bound: 76.478
Point estimate: (62.532 + 76.478)/2 = 69.505
The point estimate used to estimate the mean height of all adult males in Idaho is 69.505 inches.
If you would like to solve (g ° f)(x), you can
calculate this using the following steps:<span>
(g ° f)(x) = g(f(x))
(g ° f)(x) = g(f(x)) = g(3x) = 2 * 3x = 6x
<span>The correct result would be 6x.</span></span>
