1. Calculate the area under curve for the following values (14 points)

= 14,000

= 1500

X = 16000 and 13000

A. Calculate the area above X =16000

1. Find z value for X = 16000
2. For the calculated z value find the table value and multiply by 100
3. Area above X=16000 = 100 - the answer for step

B. Area below X = 16000

Step 1 and 2 of section (a)

C. Area between mean and X =16000

Step 1 and 2 of section (a)

To find area between mean and X = Your answer for step 2 - 50

D. 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

E. Area above X = 13000

Step 1 and 2 same as (Section d)

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

F. Area between X = 13000 and mean

Step 1 and 2 same as section d

Area between X=13000 and mean = 50 - answer for step 2

G. Area between X = 13000 and X = 16000

Answer for section C plus answer for Section F
