what is the range of the boys?
what is the median of the girls?
boys key : 1 4 represents 41 marks
girls key : 4 0 represents 40 marks

Explanation:

Step1: List boys' sit-up counts

Using the key, boys' values: $2, 10, 14, 21, 24, 29, 30, 33, 35, 38, 38, 41, 45$

Step2: Calculate boys' range

Range = Max - Min
$\text{Range} = 45 - 2 = 43$

Step3: List girls' sit-up counts

Using the key, girls' values: $5, 6, 9, 10, 14, 26, 32, 33, 33, 40, 47$

Step4: Find girls' median

Sort values, pick middle term (6th value)
$\text{Median} = 26$

Answer:

Range of the boys: 43
Median of the girls: 26
