Question

For this problem, carry at least four digits after the decimall in your caloulations. A random sample of 5380 permanent dwellings on an entire reservation showed that 1557 were traditional hogans. on of all permanent dwellings on the entire reservation that are traditional hogans. Find a point estimate for p. (Round your answer to four dedimal places.) (b) Find a 99% confidence interval for p. (Round your answer to three decimal places.) lower limit upper limit 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. 0 99% 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. 0 í % 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 Yes, the conditions are satisfied. This is important because it allows us to say that f is approximately normal. No, the conditions are not 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 binomial. No, the conditions are not satisfied. This is important because it allows us to say that f is approximately normal
