3. You would like to estimate the proportion of student loan debts that are in default. You randomly select 211 people who have student loans and find that 25 are in default.
A. Construct a 95% confidence interval to estimate the proportion of student loans that are in default. (Round your sample proportion to 4 decimal points as well as round your margin of error to 4 decimal points. For example, .23916 would be .2392 and this represents 23.92%. State the answer as an interval – for example, 27.36% to 31.43%).
B. Using the same confidence level, you would like the margin of error to be with 3%, how many people with student loans should you sample?

Do you wear a seatbelt? A study would like to estimate the
population proportion of 12th graders who wear a seatbelt. To do
so, a random sample of 1168 12th graders were selected and 710
claimed they use a seatbelt.

A university would like to estimate the proportion of fans who
purchase concessions at the first basketball game of the season.
The basketball facility has a capacity of 3500 and is routinely
sold out. It was discovered that a total of 300 fans out of a
random sample of 500 purchased concessions during the game.

fans who purchased concessions during the game. The 95% confidence
interval to estimate the proportion...

A university would like to estimate the proportion of fans who
purchase concessions at the first basketball game of the season.
The basketball facility has a capacity of 3,500 and is routinely
sold out. It was discovered that a total of 200 fans out of a
random sample of 400 purchased concessions during the game.
