Solution :
It is given that a psychologist wants to determine the difficulty of the task influences on the estimate of how long people spend working on it.
Now we have to describe a experiment by using a completely randomized design and learn the effect of the difficulty on the estimated time is by randomly assigning 15 students to a Group 1 of easy mazes and other 15 students to the second group 2 of hard mazes. And then we compare the time estimates of the two groups.
A cube has 6 sides.
Find 1 side:
1 side = 2/3 x 2/3 = 4/9
Find 6 sides:
6 sides = 4/9 x 6 = 8/3 = 2 2/3 ft²
Answer: 2 2/3 ft²
The 4 is the tenth million place
