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

Answer:
-4 is the anwser
Step-by-step explanation:
The points on the line are points B and D
<h3>How to determine the points on the line?</h3>
The equation is given as:
y = x + 4
The above means that the output value is 4 more than the input value
Using the above rule, the points that satisfy the equation are:
B) 2, 6 and D) 2, 4
This is so because:
6 = 2 + 4
4 = 2 + 2
Hence, the points on the line are points B and D
