Refer to Exercise 6.6 on p. 215 in the 4th edition of OpenIntro Statistics. Instead of doing the two parts therein, determine if the following statements are true or false, and explain your reasoning. We are 95% confident that 63% to 69% of the 1018 American adults surveyed thought licensed drivers should be required to retake their road test once they turn 65. We are 95% confident that 63% to 69% of American adults thought licensed drivers should be required to retake their road test once they turn 65. If we take many random samples of American adults of size 1018 each, and for each sample, calculated the percentage who thought licensed drivers should be required to retake their road test once they turn 65, 95% of those sample percentages will be between 63% and 69%. The margin of error at a 99% confidence level would be higher than 3%.
