Answer 1

b) you can remove 55 and it'll stay the same

Answer 2

median is the number in the middle when arranged in numerical order
32,46,50,55,60,71,80
median is currently 55
if there is an odd number of numbers, we have to take the average of the ones in the middle

find a and b that are next to each other such that their average is 55
50 and 60 average is 55
so take out 55


answer is B
