Question

hi can some one help me answer this i cant figure it out

Answer 1

Hello the answer is c) 70

The answer is 70 as u see, 75 members were asked, 16 of them chose running on treadmill

If u calculate, 20% of 75 is 15.

So with reasons, we will see what 20% of 350 is

20% of 350 is 70.

Which is estimated with reasons as to how many percent of each group chose running on treadmill.

Hope this helps :)

Answer 2

We have to find mean because they asked to estimate
15 ( because treadmill running members are 15) divided by 75( because sample members are 70) multiplied by 350 ( total gym members are 350)
15/75*350=70
So the answer is 70
