Dayton: 77, 79, 82, 85, 85, 86, 87, 88, 90, 91
Laredo: 79, 80, 81, 82, 84, 86, 87, 88, 88, 92
The median for both data sets is the middle value:
For Dayton: 86
For Laredo: 86
Therefore, both cities have the same median daily high temperature of 86°F. So, none of the provided responses are correct.
Arranging the data in numerical order:
Dayton: 77, 79, 82, 85, 85, 86, 87, 88, 90, 91
Laredo: 79, 80, 81, 82, 84, 86, 87, 88, 88, 92
Calculating the median for each data set:
For Dayton (with 10 data points): median = (86 + 87) / 2 = 86.5
For Laredo (with 10 data points): median = (84 + 86) / 2 = 85
Therefore, in this case, Dayton has a higher median daily high temperature than Laredo by 1.5°F (86.5 - 85).
So, the correct response would be:
Dayton has a higher median daily high temperature than Laredo by 1.5°F.
