Five hundred and eleven (511) homes in a certain southern California community are randomly surveyed to determine if they meet minimal earthquake preparedness recommendations. One hundred seventy-three (173) of the homes surveyed met the minimum recommendations for earthquake preparedness, and 338 did not. The point estimate for the population proportion of homes that do not meet the minimum recommendations for earthquake preparedness is 173 66.14% 338 66.02%
