Dee wants to estimate the percentage of campers at the camp who ride a bike at least once a week. She will survey a sample of campers to estimate this percentage.

Which option describes how she should select her sample?

She should select all of the campers in her bike club.

She should randomly select campers from the entire camp.

She should select campers that she sees riding their bikes on the weekend.

She should randomly select some of the campers that she sees riding their bikes to school.

Answer 1

She should randomly select campers period, because she wants to estimate the percentage of "campers that ride once a week" and not for example what percentage of campers who ride that ride once a week...

Answer 2

B. She should randomly select campers from the entire camp.

Explanation:

We are given that,

Dee wants to estimate the percentage of campers at the camp who ride a bike at least once a week.

So, according to the options, we have,

A. She should select all of the campers in her bike club.

This would not provide correct estimate as there may be other people who ride their bike at least a week.

C. She should select campers that she sees riding their bikes on the weekend.

This would not provide correct estimate as there may be people who ride their bikes on week days.

D. She should randomly select some of the campers that she sees riding their bikes to school.

This would not provide correct estimate as there may be people who do not ride the bike to school but to some other places.

So, she have to select the bikers randomly to get the correct estimate.

Thus, option B is correct.
