Five hundred nineteen (519) homes in a certain southern
California community are randomly surveyed to determine if they
meet minimal earthquake preparedness recommendations. One hundred
seventy-six (176) of the homes surveyed met the minimum
recommendations for earthquake preparedness and 343 did not.
Find the point estimate for the population proportion of homes that
do not meet the minimum recommendations for earthquake
preparedness. (Round your answer to four decimal places.)
Five hundred sixteen (516) homes in a certain southern
California community are randomly surveyed to determine if they
meet minimal earthquake preparedness recommendations. One hundred
seventy-nine (179) of the homes surveyed met the minimum
recommendations for earthquake preparedness and 337 did not.
Find the confidence interval at the 90% confidence level for the
true population proportion of southern California community homes
meeting at least the minimum recommendations for earthquake
preparedness. (Round your answers to three decimal places.)
