I have the following statistics problem.
Katrina wants to estimate the proportion of adult Americans who read at least 10 books last year. To do so, she obtains a simple random sample of 100 adult Americans and constructs a 95% confidence interval. Mathew also wants to estimate the proportion of adult Americans who read at least 10 books last year. He obtains a simple random sample of 400 adult Americans and constructs a 99% confidence level. Assuming both Katrina and Mathew obtained the same point estimate, whose estimate will have the smaller margin of error (Make sure to answer the following parts). 1) make up a point estimate for Katrina and Mathew's study. report the point estimate used 2) in order to have the same point estimate, what will be the number of successes in Katrina's study? what will be the number of successes in Mathew's study? 3) compute the confidence interval for both person as the problem described. who has the smaller margin of error? how can you tell?
I have the n, the ‘fish symbol’ and the confidence interval and the confidence interval critical value and the ‘fish’ symbol divided by 2
I’m struggling with the point estimate and the number of success for both and who has the smallest margin of error. I am

A town council wants to estimate the proportion of residents who
are in favor of a proposal to upgrade the computers in the town
library. A random sample of 100 residents was selected, and 97 of
those selected indicated that they were in favor of the proposal.
Is it appropriate to assume that the sampling distribution of the
sample proportion is approximately normal?

Suppose a veterinarian wants to estimate the difference between
the proportion of cat owners who are single and the proportion of
dog owners who are single. Of the pet owners that visit any of the
veterinarian clinics in her city regularly, she identifies 3872 pet
owners that exclusively have cats and 4108 pet owners that
exclusively have dogs. From this list of pet owners, she surveys
149 randomly selected cat owners and 126 randomly selected dog
owners and asks each...

Suppose the prime minister wants an estimate of the proportion
of the population who support his current policy on health care.
The prime minister wants the estimate to be within 0.21 of the true
proportion. Assume a 90% level of confidence. The prime minister's
political advisors estimated the proportion supporting the current
policy to be 0.48. (Round the intermediate calculation to 2
decimal places. Round the final answer to the nearest whole
number.)

A travel agent wants to estimate the proportion of vacationers
who plan to travel outside the United States in the next 12 months.
A random sample of 130 vacationers revealed that 40 had plans for
foreign travel in that time frame. Construct a 95% confidence
