Answer:
B. False
Explanation:
We have that both studies have the same production for what the first part of the statement mentions.
"A repeated-measures study and an independent-measures study both produces a t statistic with df = 20"
And they ask us if it is false or true, if one produces more than the other.
Starting from the first statement, the second statement is false because they produce the same, therefore they will be the same subjects.
