Part a)

For this problem, carry at least four digits after the decimal in your calculations. Answers may vary slightly due to rounding.

 

A random sample of 5360 permanent dwellings on an entire reservation showed that 1550 were traditional hogans.

 

(a) Let p be the proportion of all permanent dwellings on the entire reservation that are traditional hogans. Find a point estimate for p. (Round your answer to four decimal places.)

 

 

(b) Find a 99% confidence interval for p. (Round your answer to three decimal places.)

Part B)

In a survey of 1316 people, 926 people said they voted in a recent presidential election. Voting records
show that 68% of eligible voters actually did vote. Given that 68% of eligible voters actually did vote, find
the probability that among 1316 randomly selected voters, at least 926 actually did vote, then determine
what the results suggest.
OA. People are being honest because the probability of P(x2926) is at least 1%.
B. Some people are being less than honest because P(x2926) is less than 5%.
Oc. People are being honest because the probability of P(x2926) is less than 5%.
OD. Some people are being less than honest because P(x2926) is at least 1%.
