Question

A survey of 250 homeless persons showed that 14 were veterans. Find a point estimate for the population proportion of homeless persons who are veterans.

Answer 1

`\hat p =(14)/(250)= 0.056`

And for this case that represent the 5.6% of the homeless persons who are veterans

Explanation:

We know that in a survey of 250 homeless persons 14 were veterans. We can find the estimated proportion of homeless persons who are veterans with the following formula:

`\hat p =(X)/(n)`

The last one is an unbiased estimator of the true population proportion p

And replacing the info given we got:

`\hat p =(14)/(250)= 0.056`

And for this case that represent the 5.6% of the homeless persons who are veterans
