Question

Join me on my way to play for school play on the way

Answer 1

From the question,

we are given

sample size = 200

number of favourable responses =110

Population = 3,000

Let the number of people = x

This implies that from the given information we have

`\frac{number\text{ of favourable response}}{sample\text{ size}}=\frac{number\text{ of people}}{population}`

This gives

`(110)/(200)=(x)/(3000)`

solving for x we have

`\begin{gathered} 200x=110*3000 \\ 200x=330000 \\ x=(330000)/(200) \\ x=1650 \end{gathered}`

Therefore, the number of people who preferred Brand Z are 1650
