- 1The standard normal probability table is explicitly formatted to provide area data only for the continuous interval from a lower limit of z = -3.09 to an upper limit of z = +3.09.✓
- 2The standardized normal distribution provides a universal framework for various normal curves by ensuring the population mean is 0 and the standard deviation is 1.
- 3If a required interval for a standardized variate spans across the mean (one limit is negative and the other is positive), the total probability is the sum of the areas for each limit.
- 4To determine the probability of a variate falling between two limits that are both on the same side of the mean, the areas corresponding to both limits must be subtracted from one another.
Correct answer
The standard normal probability table is explicitly formatted to provide area data only for the continuous interval from a lower limit of z = -3.09 to an upper limit of z = +3.09.
