Question

Standard normal distribution has mean _________ and standard deviation _________.

A. [infinity], 1
B. 1, [infinity]
C. 1, 1
D. 0, 1

Answer 1

The standard normal distribution has a mean of 0 and a standard deviation of 1. Z-scores can be calculated to compare scores across different data sets. A Z-Table can be used to find probabilities for different intervals or values.

Step-by-step explanation:

The standard normal distribution has a mean of 0 and a standard deviation of 1. It is denoted as Z ~ N(0, 1).

Z-scores can be calculated to determine how many standard deviations a value is from the mean, allowing for comparison of scores across different data sets with different means and standard deviations.

The area under the standard normal curve can be determined using a Z-Table, providing probabilities for different intervals or values.
