Final answer:
The point estimate for the population proportion of homes that do not meet the minimum recommendations for earthquake preparedness is 66.19%.
Step-by-step explanation:
The point estimate for the population proportion of homes that do not meet the minimum recommendations for earthquake preparedness can be found by dividing the number of homes that do not meet the recommendations by the total number of homes surveyed. In this case, 338 homes out of 511 do not meet the minimum recommendations. So the point estimate is:
Point estimate = 338 / 511 ≈ 0.6619 or 66.19%
