Question 1
A normal model allows us to use a Z-score and the Normal Distribution Calculator to find the
probability. So, before we can proceed, we need to determine whether conditions are met to use a
normal model.
Check the normality conditions.
Enter the smaller number you found when checking conditions. (You'll enter the larger number in the
next question)
Question 2
In the previous question, you checked the normality conditions and entered the smaller number you
found. Now, enter the larger number you found when checking conditions.
