Option b.
Step-by-step explanation:
Given that a repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10
A matched pair hypothesis test is conducted for the difference in the means for the pairs.
If 11 pairs i.e. 22 entries are compared thenwe have degrees of freedom = 11-1 =10
b. 11 for repeated and 22 for matched
is right answer.
Note: The degrees of freedom (DF) is:
DF = n - 1
where n is the number of paired observations.
