You read an online article which states that 43% of Canadian adults regularly take a daily multivitamin. You claim that the actual percentage is different from what the article states. You take a random sample of 115 Canadian adults and find that 46 of them regularly take a daily multivitamin. Use this information to answer the questions below. Remaining time: 72: 13 (min:sec) a. Suppose you wish to perform a hypothesis test of your claim. Select the most appropriate null and alternative hypotheses for this hypothesis test. OA.110:L 0.43 0B. 0.43 oc. 00. : P 0.43 : = 43 OH. : 43 0.43 lla:i 0.43 Ha:p 0.43 b. To assess your hypotheses, you wish to compute a bootstrap-based confidence interval from your sample. Which of the following uses of the quantile() function would produce the correct interval bounds for a 96% bootstrap-based confidence interval? C) A. c(quantile(B$mean, 0.01), quantile(B$mean, 0.99)) C) B. c(quantile(B$mean, 0.02), quantile(B$mean, 0.98)) C) C. c(quantile(B$mean, 0.02), quantile(B$mean, 0.96)) C) D. c(quantile(B$mean, 0.04), quantile(B$mean, 0.96)) c. After performing the bootstrap, you use it to compute a 96% confidence interval of (0.30487, 0.49513). What conclusion can be made based on this interval? Because the null value of regularly take a daily multivitamin is v captured by the confidence interval, we should ? v from what is stated in the article. v 0 and conclude that the proportion of Canadian adults who
