Answer:
B. On average, city A was warmer than city B.
Explanation:
Write the temperature for each city in ascending order:
City A
80 82 82 83 84 85 85 85 89 90
City B
71 76 77 78 78 78 84 85 91 98
City A:
The range = 90 - 80 = 10
Median = 84.5 (the mean between 84 and 85)
Mean
Mode = 85
City B:
The range = 98 - 71 = 27
Median = 78 (the mean between 78 and 78)
Mean
Mode = 78
Options:
A. The temperature range between the maximum and minimum values for city A is greater than the temperature range between the maximum and minimum values for city B. - False, because 10 is not greater than 27
B. On average, city A was warmer than city B. - True, because 84.5 > 81.6
C. The median is less for city A than for city B. - False because 84.5 is not less than 78
D. The median and mode are different for city B. - False, because the median and the mode are both 78.
