Question

A portion of people in the population claim to have certain psychic powers. Specifically some people have claimed to have experienced astral projections. A group of psychologists believe that people who have experienced astral projection also have a higher likelihood of having experienced premonitions. In order to test this claim two procedures have been proposed:

Plan A: Take a sample of people who have experienced astral projection and measure the proportion of people in this group who have also experienced premonitions. Take another sample of people who have not experienced astral projection and measure the proportion of people who have experienced premonitions. Compare the two proportions.

Plan B: Take a random sample of people and compare the proportion of people who have experienced both astral projection and premonitions with the proportion of people who have experienced only premonitions.

Which of the following methods is best for testing the claim made by the psychologists?

options:

a Choose Plan A over Plan B.

b Both plans will be equally effective in producing valid results.

Neither plan will be effective in producing valid results.

d The plans cannnot be evaluated based on the information given.
