Question

For this problem, carry at least four digits after the decimal in your calculations.

A random sample of 5,080 permanent dwellings on an entire reservation showed that 1,578 were traditional hogans.

(a)

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

p̂=q̂=

(b)

Find a 99% confidence interval for p.

Find the maximal margin of error, E. (Round your answer to three decimal places.)

E =

Report the bounds from the 99% confidence interval for p. (Round your answers to three decimal places.)
