if n = 4, preal =0.80 in the direction predicted, and a = 0.051 tail, using the sign test, the power is:

0.0000

Step-by-step explanation:

The sign test can be defined as a statistical method which can be used to test for consistent differences that are in existence between pairs

Now If N is 4, Preal is 0.80 in the predicted direction, and this is a 0.05 1-tail. Using the sign test, the power is going to be 0.0000.

The Answer is :

power = 0.0000
