Step 1: Find the mean (average) of the weights.
\frac{720}{9} = 80
The mean is calculated by adding up all the numbers and dividing by the count of numbers. First, let's add up all the weights: Now, let's divide by the count of numbers, which is 9: So, the mean weight is 80 pounds.
Step 2: Find the median of the weights.
Median = \frac{76 + 91}{2} = \frac{167}{2} = 83.5
First, arrange the weights in numerical order: 53, 55, 61, 61, 76, 91, 98, 105, 120 Since there are 9 numbers, the median is the average of the 5th and 6th numbers: So, the median weight is 83.5 pounds.
Final Answer
- Mean weight: 80 pounds - Median weight: 83.5 pounds - Mode weight: None (there are two most common weights: 61 and 55)
