1. Area below X = 13000
   1. Find z value for X= 13000
   2. For the calculated z value find the table value and multiply by 100 = Area below X = 13000
2. Area above X = 13000

Step 1 and 2 same as (Section d)

Area above X= 13000 is same as 100 - answer for step 2.

1. Area between X = 13000 and mean
