Question

Determine the area under the standard normal curve that lies between   Z= -2.14. and Z=1.19 ?

Answer 1

We have to find the area under the standard normal curve that lies between Z = -2.14 and Z = 1.19

Mathematically,

we have to find

Graphically,

So, on using the standard normal table for we get

Now,

for

We know that the total area under the curve is 1.

So,

From standard normal curve we get:

Thus,
