Find the following probabilities for the standard normal distribution
Answer & Explanation
The normal distribution is symmetric about mean 0.5.
The probability that the z lies between 0 and 2.5 is equal to the area that lies under the curve from 0 and 2.5.
In the column headed by A across 2.5 the corresponding value is 0.4938.
The probability is .
So the value of from the appendix C is 0.4938.
The value of
Aswer is 0.0062.
