To find the range, mean, and median of the given weights, we need to arrange them in ascending order first:

38, 39, 41, 42, 43, 45, 47, 48, 50, 55

Range = Highest Value – Lowest Value

= 55 – 38

= 17

Mean: To find the mean, we sum up all the values and divide by the total number of values.

Mean = (38 + 39 + 41 + 42 + 43 + 45 + 47 + 48 + 50 + 55) / 10

= 448 / 10

= 44.8

Median: The median is the middle value in a sorted set of numbers. If there is an even number of values, the median is the average of the two middle values.

Median = (43 + 45) / 2

= 44

Therefore, the range of the weights is 17 kg, the mean is 44.8 kg, and the median is 44 kg.
