Solutions
Expert Solution
Finding the areas under a standard normal curve by direct integration is a very tedious process. So, generally a standard normal table also called as z-table is used for calculating the areas under the standard normal curve.
If z-score ≥ 0, a standard z-table is used
If z-score < 0, a negative z-table is used
