Step-by-step explanation:
<u>Composite Function</u>
Given f(x) and g(x) as real functions, the composite function is defined as:
It can be found by substituting g into f.
We are given the functions:
f(x) = -x + 3
g(x) = -x -1
Find

Answer:
The value of the test statistic is
Step-by-step explanation:
Our test statistic is:
In which X is the sample mean, is the expected value,
is the standard deviation and n is the size of the sample.
The level of ozone normally found is 7.5 parts/million (ppm).
This means that
The mean of 24 samples is 7.8 ppm with a standard deviation of 0.7.
This means that
