Answer:

28*4/7

Step-by-step explanation:

4/7

   the 7 represents the 28.  28 is a multiple of 7.

<u>28</u>  *   <u>4</u>   =     <u>112</u>   =   16

 1        7           7

<u><em>there are 16 girls</em></u>

At a local high school football game, 150 randomly selected people were surveyed about the location of the concession stand. 108
Nesterboy [21]

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 p\¨.

Where

p\¨ = \frac{x}{n}

Where n represents the size of the sample and represents the number of favorable cases.

We know that n = 150 and x = 108.

Then we can estimate p by the estimator p\¨

p\¨= \frac{108}{150}

p\¨ = 0.72
