Answer:
or 9/20x + 12
Step-by-step explanation:
We can start by grouping like terms:
3/5x - 3/20x + 19 - 7.
We can add similar elements:
9/20x + 19 - 7.
Multiplying gives:
9x/20 + 19 - 7.
Adding and subtracting:
9/20x + 12
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.
