15 degrees below zero = -15
25 degrees above zero = 25
25 + 15 = 40
It rose 40 degrees.
Answer: 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*).
