Question

If the area of standard normal curve between z = 0 to z = 1 is 0.3413, then the value of ∅ (1) is

Answer 1

Step-by-step explanation:

∅(1) = Area between -infinite to 0 + Area between 0 to 1

= 0.5 + 0.3413

= 0.8413

Answer 2

The value of ∅(1) = 0.8413

Given :

The area of standard normal curve between z = 0 to z = 1 is 0.3413

To find :

The value of ∅(1)

Solution :

Step 1 of 2 :

Write down the given data

Here it is given that the area of standard normal curve between z = 0 to z = 1 is 0.3413

Step 2 of 2 :

Find the value of ∅(1)

∅(1)

= The area of standard normal curve between z = - ∞ to z = 1

= [ The area of standard normal curve between z = - ∞ to z = 0 ] + [ The area of standard normal curve between z = 0 to z = 1 ]

= 0.5 + 0.3413

= 0.8413
