A repeated-measures experiment and a matched-subjects experiment each produce a t statistic with df = 10. How many individuals participated in each study?a. 11 for repeated and 11 for matchedb. 11 for repeated and 22 for matchedc. 11 for repeated and 12 for matchedd. 12 for repeated and 12 for matched

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.

y > 1/3x

y < = -x + 4

hope this : )
