Step 1 :Given the data set [48,35,28,41,42,37,36,40,35,29,46,33].
Step 2 :First, sort the data set in ascending order to get [28, 29, 33, 35, 35, 36, 37, 40, 41, 42, 46, 48].
Step 3 :Since the data set has an even number of observations, the median is the average of the 6th and 7th numbers in the sorted data set.
Step 4 :Calculate the average of the 6th and 7th numbers, \( \frac{36 + 37}{2} = 36.5 \).
Step 5 :So, the median of the data set is \(\boxed{36.5}\).
