1. Labrador Retriever - Average weight: 55-80 pounds
2. German Shepherd - Average weight: 50-90 pounds
3. Golden Retriever - Average weight: 55-75 pounds
4. Bulldog - Average weight: 40-50 pounds
5. Beagle - Average weight: 20-30 pounds
6. Poodle - Average weight: 45-70 pounds
7. Boxer - Average weight: 50-80 pounds
8. Dachshund - Average weight: 11-32 pounds
9. Chihuahua - Average weight: 2-6 pounds
Mean: (80 + 90 + 75 + 50 + 30 + 70 + 80 + 32 + 6) / 9 = 52.11 pounds
Median: In ascending order - 30, 32, 40, 45, 50, 55, 70, 75, 80, 80, 90. Median = 55 pounds
Mode: 80 pounds
In this case, the mean would be the best measure of central tendency as it takes into account all the weights of the different breeds and provides an average that reflects the overall distribution of data. The median may be slightly skewed in this case due to certain breeds with higher weights, while the mode may not be as representative of the overall data set.

To find out how much a 10th dog would have to weigh in order for the average weight to be 250 pounds, we can use the formula for calculating the mean.
We know that the current average weight of the 9 dogs is 52.11 pounds. Let the weight of the 10th dog be represented by x.
Now, we can set up an equation to solve for x:
(80 + 90 + 75 + 50 + 30 + 70 + 80 + 32 + 6 + x) / 10 = 250
Solving for x:
(493 + x) / 10 = 250
493 + x = 2500
x = 2500 - 493
x = 2007
Therefore, the 10th dog would have to weigh 2007 pounds for the average weight of all 10 dogs to be 250 pounds.
