BOX PLot: 

 

Kendra surveyed a random sample of 100 members of a local gym. She found that 40% of the gym members surveyed had taken a yoga class. Kendra wanted to know if it is plausible that 50% of the entire population of gym members had taken a yoga class.

Kendra performed 100 trials of a simulation. Each trial simulated a sample of 100 gym members under the assumption that 50% of the population had taken a yoga class. The dot plot shows the results of the simulations.

What is the best conclusion for Kendra to make based on the data?

 

A) It is not plausible that 50% of the population had taken a yoga class because the data shows that a sample proportion of 40% is likely.

B) It is not plausible that 50% of the population had taken a yoga class because the data shows that a sample proportion of 40% is unlikely.

C) It is plausible that 50% of the population had taken a yoga class because the data shows that a sample proportion of 40% is unlikely.

D) It is plausible that 50% of the population had taken a yoga class because the data shows that a sample proportion of 40% is likely.
