Question 1a)
It is given that
The region under the standard normal curve that lies to the left of -1.92 has area 0.0274289.
Now, we have to find the area under the standard normal curve, that lies to the right of 1.92.
We know, from the property of normal distribution, that a standard normal curve is symmetric about zero.
This means, the area to the right of zero, is same as the area to the left of zero; ie.
And this also means
Where, h is any real value.
So, when h=1.92, we can conclude that
Now, it is given P(z<1.92)=0.0274289.
So, we can say
The answer is
The area under the standard normal curve that lies to the right of 1.92 is 0.0274289.

According to a standard normal table, the area under the standard normal curve to the left of 1.37 is 0.9147. Without consulting a standard normal table or using technology, determine the area under the standard normal curve to the left of negative 1.37. The area to the left of 1.37 is? I personally thought you do 1-0.9147= .0853 but could be wrong. (type as an integer or a decimal)
