Question

Dayton: 77,85,87,90,85,79,86,91,88
Laredo: 81,79,80, 86,88,92,88,84,87

Answer options:

A). Laredo has a higher median daily high temperature than Dayton by 1°F

B). Laredo has a higher median daily high temperature than Dayton by 0.5°F

C). Dayton has a higher median daily high temperature than Laredo by 0.5° F

D). Dayton has a higher median daily high temperature than Laredo by 0.3°F

Answer 1

To find the median daily high temperature for each city, we first need to order the temperatures from lowest to highest.

For Dayton:
77, 79, 85, 85, 86, 87, 88, 90, 91

For Laredo:
79, 80, 81, 84, 86, 87, 88, 88, 92

Since we have an odd number of temperatures for both cities, the median will be the middle number when ordered.

For Dayton, the median is 86°F
For Laredo, the median is 87°F

Therefore, the correct answer is:

C). Dayton has a higher median daily high temperature than Laredo by 0.5°F.
