To determine which city has a higher median daily high temperature, we first need to calculate the median for both Dayton and Laredo.
Here are the daily high temperatures for each city:
Dayton: 77, 82, 85, 87, 90, 85, 79, 86, 91, 88
Laredo: 81, 79, 80, 86, 88, 92, 82, 88, 84, 87
Step 1: Sort the temperatures in ascending order.
For Dayton:
- Sorted: 77, 79, 82, 85, 85, 86, 87, 88, 90, 91
For Laredo:
- Sorted: 79, 80, 81, 82, 84, 86, 87, 88, 88, 92
Step 2: Calculate the median.
For a set of 10 numbers, the median is the average of the 5th and 6th numbers.
-
Dayton:
- The 5th number is 85 and the 6th number is 86.
- Median = (85 + 86) / 2 = 85.5°F.
-
Laredo:
- The 5th number is 84 and the 6th number is 86.
- Median = (84 + 86) / 2 = 85°F.
Step 3: Compare the medians.
- Median for Dayton: 85.5°F
- Median for Laredo: 85°F
Step 4: Determine the difference.
Difference = 85.5°F - 85°F = 0.5°F
Thus, Dayton has a higher median daily high temperature than Laredo by 0.5°F.
The correct response is: Dayton has a higher median daily high temperature than Laredo by 0.5° F.
