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: Option A

192 people[

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 =(X_B)/(n)`

Where

`X_B=32`

`n=125`

`P =(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`

Answer 2

The correct answer option is 192.

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 =
`(32)/(125) * 7 5 0` = 192
