Answer: G, 32
Explanation:
The median means the middle, which means that t is the middle of a given group. With this knowledge, we can order the numbers to get:
22, 22, 32, t, 41, 64, 78.
Since the amount of digits given is odd, t can be any range from 32-41, as opposed to if the number of digits given was even, in which you would need to find the average distance. In this case, we are finding the lowest value of t, and the lowest value from 32-41 is 32, thus making our answer G, 32.
