Since

we know our function is

.
To solve, substitute the given value:
Answer:
3^3 * 7^r has (3 + 1)*(r + 1) = 16 factors.
So r must be 3.
#11 and #12 have no solutions, #13 has a solution which is 14
Answer:
The point estimate of the population mean for the confidence interval of (15,32) is 23.5
Step-by-step explanation:
We are given the following information in the question:
Confidence interval for population mean is (15, 32).
We have to find the point estimate for population mean.
Formula:

The point estimate of the population mean for the confidence interval of (15, 32) is 23.5
