What are the mean and standard deviation of the standard normal distribution?

Mean of 0 and standard deviation of 1

Explain what a z-score represents.

A z-score represents the number of standard deviations a data point is from the mean of its distribution.

The area given in the table for the calculated z-score directly represents the probability that x is less than the specified value.

Subtract the area found in the table (corresponding to the z-score) from 1.

I can use Table A to find probabilities associated with a standard normal distribution.

1
The standard normal distribution (z-distribution) has a mean (µ) of 0 and a standard deviation (σ) of 1.
2
To convert a value, x, from a normal distribution to a z-score, use the formula z = (x-μ)/σ.
3
To find the area between two z-values, subtract the smaller area from the larger area obtained from the z-table.
