How does each of the following affect the power of a planned study? (a) a larger predicted difference between the means of the populations (b) a larger population standard deviation (c) a larger sample size (d) using a more extreme significance level (for example, 0.01 instead of 0.05) (e) using a two-tailed test instead of a one-tailed test

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12

the answer i believe is 27 units.
