n USE SALT
(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 answers to three decimal places.)

Give a brief interpretation of the confidence interval.
O 1% of the confidence intervals created using this method would include the true proportion of traditional
hogans.
99% of the confidence intervals created using this method would include the true proportion of traditional
hogans.
1% of all confidence intervals would include the true proportion of traditional hogans.
99% of all confidence intervals would include the true proportion of traditional hogans.
(c) Do you think that np > 5 and ng > 5 are satisfied for this problem? Explain why this would be an important
consideration.
O No, the conditions are not satisfied. This is important because it allows us to say that p is approximately
binomial.
Yes, the conditions are satisfied. This is important because it allows us to say that p is approximately
binomial.
O Yes, the conditions are satisfied. This is important because it allows us to say that p is approximately normal.
O No, the conditions are not satisfied. This is important because it allows us to say that p is approximately
normal.
