The Journal of Travel conducted research by taking two large a) The mean cost of a one-day trip for Group A is $|:| and for Group B $|:|_ groups (viewed as populations) to determine whether there are differences in the characteristics of the two groups of holiday travellers: [Group A] travellers that are less than 50 years old. b) For which set of travelers would the median be a better measure of central tendency than the mean? The standard deviation of the cost of a one-day trip for Group A is (rounded to nearest cent) $ and for Group B $ [Group B] travellers that are 50 or more years old. One item of interest was the amount spent for a one-day trip. The O A. All travellers results are shown below. 0 B. Over 50 Group B Cost of one-day trip Group A: Under 50 Group B: Over 50 O c.
