Answer

Explanation:

Step1: Count the data - points

Count the number of values in the stem - and - leaf plot. There are 3 + 4+6 + 3+3=19 values.

Step2: Determine the position of the median

For a set of (n) values (where (n = 19) is odd), the median is the (\left(\frac{n + 1}{2}\right))-th value. (\frac{19+1}{2}=10) - th value.

Step3: List out the data in ascending order

The data in ascending order: 22, 23, 29, 31, 34, 36, 38, 40, 43, 45, 47, 48, 49, 53, 57, 58, 62, 63, 65.

Step4: Identify the median

The 10 - th value in the ordered list is 45.

Answer:

45
