Answer:
The upper endpoint of the 99% confidence interval for population proportion is 0.13.
Step-by-step explanation:
The confidence interval for population proportion is:

<u>Given:</u>
<em>n</em> = 1000
= 0.102

*Use the standard normal table for the critical value.
Compute the 99% confidence interval for population proportion as follows:

Thus, the upper limit of the 99% confidence interval for population proportion is 0.13.
Let s be the son's age 15 yeasr ago and m the mother's age that year.

We also know that:

Plotting vallues:

Remember that they were that age 15 years ago.
So their actual age is 30 and 60.
