The numbers of passengers on 9 airline flights were 22, 33, 21, 28,22, 31,44, 50, and 19. The standard deviation of these 9 numbers is approximately equal to 10.2.
(a)Find the mean, median, mode, range, and interquartile range of the 9 numbers.
(b)If each flight had had 3 times as many passengers, what would have been the mean, median, mode, range, interquartile range, and standard deviation of the 9 numbers?
(c)If each flight had had 2 fewer passengers, what would have been the interquartile range and standard deviation of the 9 numbers?
选项
答案
(a)mean = 30, median = 28, mode = 22,
range = 31, interquartile range =17
(b)mean = 90, median = 84, mode = 66,
range = 93, interquartile range = 51,
standard deviation = 3[*]≈30.7
(c)interquartile range =17, standard deviation≈10.2
