One way is to solve for the inverse of the first function
remember, to solve, replace f(x) or g(x) with y, switch x and y, solve for y and replace it with
A.
nope, not A
<h3>What is the inverse function?</h3> The inverse function of a function f is a function that undoes the operation of f. The inverse of f exists if and only if f is bijective, and if it exists, is denoted by
B.
nope, not the same
not B

Answer:
The 84% confidence interval for the population proportion that claim to always buckle up is (0.74, 0.80).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of .
They randomly survey 387 drivers and find that 298 claim to always buckle up.
This means that
84% confidence level
So , z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 84% confidence interval for the population proportion that claim to always buckle up is (0.74, 0.80).
