The Journal of Travel conducted research by taking two large groups (viewed as a) The mean cost of a one-day trip for Group A is $ and for Group populations) to determine whether there are differences in the characteristics of the two groups of holiday travellers: BS. [Group A] travellers that are less than 50 years old. The standard deviation of the cost of a one-day trip for Group A is [Group B] travellers that are 50 or more years old. (rounded to nearest cent) $ and for Group B S One item of interest was the amount spent for a one-day trip. The results are shown below. b) For which set of travelers would the median be a better measure of central tendency than the mean? Cost of one-day trip Group A: Under 50 years old Group B: Over 50 years old (n=480) (n=325) O A. All travellers $0 up to 50 6% 1% 50 up to 100 13 5 O B. Under 50 Group A 100 up to 200 21 9 O C. Over 50 Group B 200 up to 300 29 13 O D. Neither group 300 up to 400 11 20 400 up to 500 12 c) For Group A, 384 of those surveyed would have spent less than 500 up to 750 2 O A. $300 750 up to 1000 1000 up to 2000 O B. $500 - N 2000 up to 3000 O C. $400 O D. $750 (Base your answer on results obtained by using your calculator.) d) The coefficient of variation for Group A is and for Group B is Group B is relatively more variable than Group A True O False
