Answer:
Option B
<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
We know that
(1/4) hour---------> 0.25 hour
if the pump r<span>ecirculate 75 gallons of water in -------------> 0.25 hour
X </span>gallons of water in-----------------------------------------> 1 hour
X=75/0.25----------> x=300 gallons /hour
the answer is 300 gallons /hour
Answer:
