Question

Use the table from a random survey about the preferred service for streaming movies. Out of 750 people, how many would you expect to prefer Company B?

Answer 1

Answer:

The correct answer option is 192.

Step-by-step explanation:

We are given the results of a random survey about the preferred service for streaming movies.

We are to find the number of people we would expect to prefer Company B.

Number of people using service B = 32

Total number of people = 125

Number of people expected to prefer Company B = $\frac{32}{125} \times 7 5 0$ = 192

Answer 2

Answer: Option A

192 people[

Step-by-step explanation:

From the participation survey

$n =75+32+18=125$ people

Among these 125 people, only 32 preferred the company B

Now assuming that this sample is representative of the total population, then the probability that a randomly selected person prefers company B is:

$P =\frac{X_B}{n}$

Where

$X_B=32$

$n=125$

$P =\frac{32}{125}$

$P =0.256$

Finally, the expected number of people who prefer company B is:

$E = P * m$

Where m is the number of people in the total population. $m = 750$

$E=0.256*750$

$E=192\ people$
