A study reported that about half of young adults continue to text and drive, despite the dangers. To find out if this applies to teens, you asked an SRS of 30 classmates if they texted while driving, and 13 responded "Yes.β To see if this result is surprising, you need to conduct a simulation to estimate the probability of obtaining a sample result as low as yours given that the young adult study is correct. Which is a correct method to model expected results based on the studyβs claim?
Using a coin, let heads = yes and tails = no; flip the coin 30 times, recording the proportion of heads; and perform many trials.
Using a die, let evens = yes and odds = no; roll the die 30 times, recording the proportion of times evens occur; and perform many trials.
Using a die, let 1β2 = yes and 3β6 = no; roll the die 30 times, recording the proportion of times 1β2 occur; and perform many trials.
Using a die, let 1β3 = yes and 4β6 = no; roll die 30 times, recording the proportion of times 1β3 occur; and perform many trials.
