A. 10, 40
B. 10, 50
C. 10, 60
D, 60, 10

Answer 1

D, 60, 10

Step-by-step explanation:

A 3 x 2 factorial is a design that considers two different factors at 3 and 2 levels. Since at least 10 subjects in needed per treatment condition, to get the total number of the subject is calculated below;

no of plots experimental plots therefore;

3 x 2 = 6

since 10 subjects in needed per experimental plot, total number of subjects therefore;

6 x no of subjects

6 x 10 = 60subject.

10 subjects will be required between the subjects version of the study.
