Replace m with each number in the given set and solve for d(m)
m = 0
d(m) = 7-2(0) = 7-0 = 7
m=1
d(m) =7-2(1) = 7-2 = 5
m = 2
d(m) = 7-2(2) = 7-4 = 3
m=3
d(m) = 7-2(3) = 7-6 = 1
The answers in order from smallest to largest are 1, 3, 5,7

Step-by-step explanation:
Answer: z-test for population mean.
Step-by-step explanation:
Given : purchase of a coin-operated laundry. The current owner claims that over the past 5 years, the average daily revenue was $675 with a standard deviation of $75.
So the null hypothesis and alternative hypothesis will be :-
It means the test will be for population mean.
We assume that this is normally distributed.
We know that we use t-test for sample size less than 30 and z-test for sample size greater than 30 .
Since the sample size is 30, so the test use here is z-test for population mean.
