Giovanna has two possible driving routes to her new workplace, and she is having a hard time figuring out which is faster. The first route is shorter, but usually has more traffic than the second route. She decided to conduct a small study. Over a period of 555 weeks, she used the first route in the first half of the week (Monday, Tuesday, and Wednesday), and the second route in the second half of the week (Thursday and Friday). Each day she recorded how long it took her to get to work, and by the end of the 555 weeks she calculated the average driving duration for each route. What type of statistical study did Giovanna use? Choose 1 Choose 1 (Choice A) A Sample study (Choice B, Checked) B Experiment (Choice C) C Observational study Is the study appropriate for the statistical questions it's supposed to answer? Mark the most suitable choice. Choose 1 Choose 1 (Choice A) A No, because there was no randomization. (Choice B) B No, because she didn’t compare the two routes with a third, neutral route. (Choice C) C Yes, because it allows to compare between the driving durations in the two routes. (Choice D) D No, because she should’ve asked someone else to drive.
