Answer:

width (C.I) ∠ width (P.I)

Step-by-step explanation:

In statistics, a confidence interval (C.I) is known as an interval estimate which is computed using the observed data that might contain the actual value of an unknown parameter. The confidence level is commonly used for estimation before examining the actual data. On the other hand, the prediction interval (P.I) is a range of values that calculate the value of a new observation by considering the existing model developed using the actual data. Therefore, the true statement is:

width (C.I) ∠ width (P.I)

Evaluate the following and show steps. f(x) = 15x – 12 and g(x) = -15x2 + 14x - 10 find g(f(7))
diamong [38]
When we have a function such as h(x) = 2x, and we want to find the value of h at a given x value, we plug in the given number for x. For example, h(3) = 2*3 = 6.

We do the same thing with g(f(7)). In this case we plug 7 into f(x) for x, then plug the result of f(7) into g(x) for x.

f(7) = 15*7 - 12 = 93

g(93) = -15*93^2 + 14*93 - 10 = -128443
