Question

2) How many male students given that their preferred superpower is super strength would you expect in a random selection of 100 high school students? Round to the nearest whole number. A) 5 6 D) 13

Answer 1

We have a total of 450 students. The number of male students that prefer super strength is 25.

So in order to estimate the number of male students that prefer super strenght among 100 random students, we can use a rule of three:

`\begin{gathered} 25\to450 \\ x\to100 \\ \\ x\cdot450=2500 \\ x=(2500)/(450)=5.55 \end{gathered}`

Rounding to the nearest whole, we can expect 6 students, so the correct option is B.
