Answer: 0.0811

Step-by-step explanation:

In the absence of complete data , the sample proportion is considered as the  point estimate of the population proportion .

Given : Sample size of people : n= 493

Number of people had hearing aids : x = 40

Let p be the proportion of people who wear hearing aids.

Now , the sample proportion : [tex]\hat{p}=\dfrac{40}{493}\approx0.0811[/tex]

Thus , the point estimate of the proportion of people who wear hearing aids si 0.0811.
