Can You Find The Percent Of Total Area Between Z = -2.49 And Z = 1.19 Under A Normal Curve That Is?

Check the values of z in the area table under the unit normal curve:

Area under z =  -2.49 is 0.4936
Area under z =   1.19 is 0.3880

Total area = 0.8816

Now, the total area under the normal curve is 1, and total area of z is 0.8816. This shows that percent of area between z = -2.49 and z = 1.19 is 88.16%.

Check the values of z in the area table under the unit normal curve:

Area under z =  -2.49 is 0.4936
Area under z =   1.19 is 0.3880

Now, Total area  = area under z on right + area under z on left

                         =  0.4936 + 0.3880 = 0.8816

You know that the total area under a normal curve is 1, and total area of z is
0.8816. Therefore, total area under z in terms of percentage is 88.16%.

Check z = 1.19. I'm guessing it's a typo. 0.3830 might be considered closer.
 
Answer should be 87.7%
