Answer:
<em>16.5 gallons per minute.</em>
Step-by-step explanation:
The given table is:
We are given this linear function in the form of table.
Let 't' be the time and W(t) be the function with which the gallons of water are changing with time.
We can use slope intercept form to find the equation.
Slope of a function:
This slope is the constant of proportionality.
i.e. the rate at which the number of gallons are changing per minute.
So, the answer is <em>16.5 gallons per minute.</em>
Answer with explanation:
Given : Sample mean =
Standard deviation :
Sample size : n = 36
Claim :
∴
Since the alternative hypothesis is two tail , then the test is two tail test.
By using a z statistic and a 0.05 level of significance. Reject if z < -1.960 or is z> 1.960.
Then , the test static for population mean is given by :-
We reject since . We have statistically significant evidence at to show that the mean amount of garbage per bin is not different from 50.
