Final answer:
The median for the given sample data is -1.5 pounds.
Step-by-step explanation:
To find the median for the given sample data, you need to arrange the weights in ascending order. The sample data consists of -4, 9, -1, -8, 7, -2, -10, and -3 pounds. Rearrange the data from smallest to largest: -10, -8, -4, -3, -2, -1, 7, 9. The median is the middle value, so in this case, it would be the average of the two middle values, -2 and -1. Adding them together and dividing by two gives us the median of -1.5 pounds.
