Breeds and weights:
1. Yorkie - 7 pounds
2. Boxer - 65 pounds
3. Plott Hound - 50 pounds
4. Poodle - 60 pounds
Mean = (7+65+50+60)/4 = 45.5 pounds
Median = (50+60)/2 = 55 pounds
Mode = There is no mode in this data
The median best describes the data because it is not influenced by extreme values like the mean, and there is no mode present.
To find the weight of the 10th dog for the average weight to be 250 pounds:
Let the weight of the 10th dog be x
(7+65+50+60+x)/5 = 250
182 + x = 1250
x = 1068 pounds
So, the 10th dog would have to weigh 1068 pounds for the average weight to be 250 pounds.
