I don’t know how to handle this Statistics question and need guidance.

Instructions:

Please remember to show ALL of your work on every problem.If there is no work to show, then include a sentence or two explaining your answer.

Here are the basic rules of showing work:

a) Each step should show the complete expression or equation rather than a piece of it.

b) Each new step should follow logically from the previous step, following rules of algebra.

c) Each new step should be beneath the previous step.

d) The equal sign, =, should only connect equal numbers or expressions.
