create a table based on your estimated x-value. from your estimated x-value, count down by 0.05 three times and count up by 0.05 three times (place your estimated value in the middle of these other values). then find the corresponding y-values for each of the equations.

y = (x+1)3 - 1
the 3 is on top of the parenthesis

y = 2x
the x is on top of the 2

To find the critical value, follow these steps.

Compute alpha (α): α = 1 - (confidence level / 100)

Find the critical probability (p*): p* = 1 - α/2.

To express the critical value as a z-score, find the z-score having a cumulative probability equal to the critical probability (p*).
