A random sample of 5080 permanent dwellings on an entire reservation showed that 1641 were traditional hogans. 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.) lower limit upper limit Give a brief interpretation of the confidence interval. 99% of all confidence intervals would include the true proportion of traditional hogans. 1% 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. o 99% of the confidence intervals created using this method 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. Yes, the conditions are satisfied. This is important because it allows us to say that is approximately normal. No, the conditions are not satisfied. This is important because it allows us to say that p is approximately binomial.
