<em>The best point estimate of the proportion of people attending the game who believe that the concession stand should be closer to the stands is:</em>
<em>p = 0.72.</em>
Step-by-step explanation:
We want to estimate the proportion of people who feel that the stand should be closer to the stands.
We have a sample of 150 people, of which 108 think that the stand should be closer to the stands.
A point estimator for the proportion p is .
Where
Where n represents the size of the sample and represents the number of favorable cases.
We know that and
.
Then we can estimate p by the estimator
