Please answer this question

1/6

Step-by-step explanation:

3 feet = 3*12 = 36

Scale factor = 6/36 = 1/6

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.
