A survey was conducted to determine the percentage of parents who would support raising the legal driving age to 18. The results were stated as 67% with a margin of error of ±3%. What is meant by ±3%? A. Three percent of the population were not surveyed. B. In the sample, the percentage of parents who would support raising the driving age is between 64% and 70%. C. The percentage of the entire population of parents who would support raising the driving age is between 64% and 70%. D. It is unlikely that the given sample proportion result could be obtained unless the true percentage was between 64% and 70%. E. Between 64% and 70% of the population were surveyed.

A 2007 survey of 980 American drivers concluded that 38% of the driving population would be willing to pay higher gas prices to protect the environment. Which of the following best describes what is meant by the poll having a margin of error of 3 percent? (a) Three percent of those surveyed refused to participate in the poll. (b) It would not be unexpected for 3 percent of the population to readily agree to the higher gas prices. (c) If a similar survey of 980 American drivers was taken weekly, a 3 percent change in each week's results would not be unexpected. (d) It is likely that between 35 percent and 41 percent of the driving population would be willing to pay higher gas prices to protect the environment.

Teens and Distracted driving paper reported that in a representative sample of 283 teens age 16 to 17, there were 74 who indicated that they had sent a text message while driving. Do these data provide convincing evidence that more than a quarter of teens have sent a text message while driving? Test the appropriate hypothesis at the 1% significance level. a) Hypotheses: b) Critical Value and Region (Draw Picture): c) Test Statistics: d) Decision and Interpretation:
