Question

A data set has a median of 89, and four of the numbers in the data set are less than median. The data set contains a total of n numbers. If n is even, and none of the numbers in the data set is equal to 89, what is the value of n?

Answer 1

This data set looks like the following:

a,b,c,d,88,90.e,f,g,h

Since n is even, the median is the average of 88 & 90, that is (88+90)/2 =89

so n= 10
