Question

A gym surveyed 100 female members. These members were chosen at random from the gym's membership database. Participants were asked the question, "Do you prefer to use the easy weight-lifting machines or the harder free weights?"
A report of the survey results stated that female members at the gym prefer the weight-lifting machines over the free weights.

Select all statements that correctly evaluate the report.

The sample is biased because it does not represent the population.

The question is not biased.

The question is biased towards a response of preferring to use weight-lifting machines.

The sample is not biased.

The question is biased towards a response of preferring to use free weights.

Answer 1

The question is biased towards a response of preferring to use weight-lifting machines because it uses the words "hard" to describe free weights and "easy" to describe the machines, and may persuade some people to choose the machine.

The sample is not biased because it doesn't choose specific women, it includes all women who visit the gym.

Answer 2

Given that there is a survey of 100 randomly selected female members of the gym about choosing between "easy weight-lifting machines or the harder free weights".

Report of the survey says that "female members at the gym prefer the weight-lifting machines over the free weights."

Now we have to select from the given statements that correctly evaluate the report.

According to me "The question is biased towards a response of preferring to use weight-lifting machines." because description of word "hard" is used for "free weights" while word "easy" is used for "machines". That may persuade some people to choose the machine.

Since 100 females are randomly selected not specifically so "The sample is not biased."

Hence final answer should have two statements:

1) The question is biased towards a response of preferring to use weight-lifting machines.

2) The sample is not biased.
