Yorkie - 7 pounds
Boxer - 65 pounds
Plott Hound - 50 pounds
Poodle - 60 pounds
Beagle - 22 pounds
Greyhound - 27 pounds
Golden Retriever - 60 pounds
Golden Doodle - 45 pounds
Chihuahua - 5 pounds
Mean: (7+65+50+60+22+27+60+45+5) / 9 = 37.11 pounds
Median: Arrange in ascending order: 5, 7, 22, 27, 45, 50, 60, 60, 65. The median is 45 pounds.
Mode: 60 pounds
The best measure of central tendency to describe the data would be the median because it represents the weight that falls exactly in the middle of the data set, making it less influenced by any outliers in the data. Since dog breeds can vary greatly in size, the median provides a good representation of a typical weight within the data set.
To find the weight of the 10th dog for the average weight to be 250 pounds, we can use the formula:
(7+65+50+60+22+27+60+45+5+x) / 10 = 250
(286+x) / 10 = 250
286 + x = 2500
x = 2214
Therefore, the 10th dog would have to weigh 2214 pounds for the average weight to be 250 pounds.
