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?

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

b. she should randomly select campers from the entire camp.

c. she should select all of the campers in her bike club.

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

The correct answer is B) she should randomly select campers from the entire camp.

The option that describes how she should select the campers is she should randomly select campers from the entire camp.

To make a correct estimation of the percentage of campers at the camp that rides a bike at least once a week, Dee has to randomly select campers from the entire camp. She cannot limit its simple to the bikers that only ride on weekends because that estimation is limited to just two days of the week, Saturday and Sunday. She cannot limit its sample to the members of her bike club because they are only a portion of the bikers. And she cannot use as a simple the bikers that ride to school because that its a partial number. So the correct option that describes how she should select the campers is she should randomly select campers from the entire camp.
