Answer:
the median value of the given data set is 30
Step-by-step explanation:
The computation of the median value is as follows:
27,28,28,29,29,29,30,30,30,31,31,31,33,34
There are 14 entries
So the mid value is 30
Hence the median value of the given data set is 30
The answer is B, trust im a math teacher :p
