OBFW Publishers A media report claims that 50 of U S teens with smartphones feel addicted to their devices A skeptical researcher believes that this figure is too high She decides to test the claim by taking a random sample of 100 U S teens who have smartphones Only 40 of the teens in the sample feel addicted to their devices Does this result give convincing evidence that the media report s 50 claim is too high To find out we want to perform a simulation to estimate the probability of getting 40 or fewer teens who feel addicted to their devices in a random sample of size 100 from a very large population of teens with smartphones in which 50 feel addicted to their devices Let 1 feels addicted and 2 doesn t feel addicted Use a random number generator to produce 100 random integers from 1 to 2 Record the number of I s in the simulated random sample Repeat this process many many times Find the percent of trials on which the number of 1 s was 40 or less Does the problem describe a valid simulation design Justify your answer O No it does not describe a valid simulation design The simulation should let 0 3 feels addicted and 4 9 doesn t feel addicted O No it does not describe a valid simulation design It does not specify that you should ignore repeating numbers when choosing integers from the random number generator O No it does not describe a valid simulation design It does not specify how many times to repeat the simulation Yes it describes a valid simulation design By letting 1 feels addicted and 2 doesn t feel addicted the simulation would model the claim that 50 of U S teens with smartphones would feel addicted to their devices No it does not describe a valid simulation design The simulation should let 0 5 feels addicted and 6 9 doesn t feel addicted
