Question

Do people pick Product A more than 50% of the time when given a choice of Product A or something else? I sample 40 people and find that 28 of them picked Product A (28/40=70% picked product A). I use the applet to investigate whether or not people pick Product A more than 50% of the time in the long run. I run 100 repetitions.

Each dot in the simulation represents ________. (pick the correct answer)

A) The number of people who picked product A in a set of 40 people sampled, assuming that people pick product A 70% of the time in the long run.

B) The number of people who picked product A in a set of 40 people sampled, assuming that people pick product A more than 70% of the time in the long run.

C) The number of people who picked product A in a set of 40 people sampled, assuming that people pick product A 50% of the time in the long run.

D) The number of people who picked product A in a set of 40 people sampled, assuming that people pick product A more than 50% of the time in the long run.

Answer 1

Since our sample size is 40 and we are using the applet to check our hypothesis, we can say that the dots represents those people who are picking product A and are in the sample. Also, we are checking, by running 100 repetitions, whether or not the percentage of such kind of people is more than 50% or not in the long run.
Hence, our answer is - The number of people who picked product A in a set of 40 people sampled, assuming that people pick product A more than 50% of the time in the long run.
