21. Do men really spend more money on St. Patrick's Day as compared to women? A recent survey found that men spend an average of $43.87 while women spend an average of $29.54. Assume that these data were based on a sample of 100 men and 100 women and the population standard deviations of spending for men and women are $32 and $25, respectively. Which of the following is the correct value of test statistic? A. z =-3.53 B. tar = 3.53 C. tar = -3.53 D. z = 3.53 22. A recent Health of Boston report suggests that 14% of female residents suffer from asthma as opposed to 6% of males. Suppose 250 females and 200 males responded to the study. Which of the following are an appropriate null and alternative hypotheses to test whether the proportion of females suffering from asthma is greater than the proportion of males? A. Ho: p1 - P2 S0, HA: P1 - p2 > 0 B. Ho: P1 - P2 2 0, HAP1 - P2 < 0 C. Ho: P1 - P2 = 0, HA: P1 - p2 #0 D. Ho: p1 - p2 > 0, HA: P1 - p2 50 23. What type of data should be collected to compare the likelihoods of two candidates winning their elections when the candidates are running in different elections? A. Matched-pairs sampling with qualitative data. B. Independent sampling with qualitative data. C. Matched-pairs sampling with quantitative data. D. Independent sampling with quantitative data.
