the statement is always true

the statement is sometimes true

the statement is always false

Answer 1

So the median of this data set is the mean of the two middle numbers, which are x+2 and x+6

Mean = ((x+2)+(x+6))/2
Mean = (2x+8)/2
Mean = x+4

We can say from this addition that if x is an odd number then the mean will also always be odd. By extension we can therefore say that the median of the set will also be odd.
Hence the answer is B
