Question

Use the following information to answer the next two exercises: 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 ______.

a. 0.6614

b. 0.3386

c. 173

d. 338

Short answer

The point estimate for the population proportion of homes that do not meet the minimum recommendations for earthquake preparedness is (b)$0.3386$

Step-by-step solution

Introduction

The number of homes surveyed met the minimum recommendations for earthquake preparedness = $173$

The number of homes surveyed doesn't meet the minimum recommendations for earthquake preparedness =$338$.

Explanation

Calculating the point estimate = $\frac{\text{Housesthatmettheearthquakepreparedness}}{\text{No.ofhousessurveyed}}$

The number of homes surveyed met the minimum recommendations for earthquake preparedness = $173$

Total number of houses surveyed = $511$

Hence the point estimate is = role="math" localid="1653890892269" $\frac{173}{511}=0.3386$
