Question details

Part I. (10 Points) Consider the following scenarios: Scenario 1: Suppose a traffic survey asks: Do you think fines for speeding should be doubled? What do you think the responses would be if there was only the options yes or no? How might these change if the question Have you ever been fined for speeding? preceded this question in the survey? In general, what could be some issues with this question and how it is worded? Scenario 2: Suppose a company that manufactures paint claims in their advertisement In a randomized comparative experiment on drying time, our paint beat out the competition! We have the fastest drying paint! Suppose the following is the actual data from the experiment done by the manufacturer Dry time in minutes for Manufacturers Paint 33.2 29.3 Dry time in minutes for Competitions Paint 335 35.6 295 354 Consider the average dry time of each paint type. Is the manufacturers claim truthful? Either way, is the advertisement misleading? Why or why not? What else could be a source of issue when it comes to this experiment? Consider bias of the experimenter and replication.
Scenario 3: In an attempt to understand the nations opinion on universal healthcare, investigators sponsored an advertisement during an American mid-morming news radio that asked viewers the following question: Should everyone have healthcare? Weigh in tonight from 4 to 6pm. Iyes, call 1-900-720-6181 fno, call 1-900-720-6182. Charge is 50 cents for the first minute. Consider the population that the investigators are trying to sample, do they obtain a representative sample from this sampling scheme? Specifically, what type of sampling scheme has been used? What type of sampling bias(s) may have occur? What else could be a source of issue when it comes to this scenario?
