The normal probabilities are calculated using the table of standard normal distribution where the mean and standard deviations are,respectively:
A)1 and 1.
B)10 and 0.
C)0 and 1.
D)0 and 10.

Question

Quizplus · Accepted Answer

The table of standard normal distribution is based on a normal distribution with a mean of 0 and standard deviation of 1. Therefore, the options that have these values for mean and standard deviation are the best choice. Option A has a mean of 1, which does not match the standard normal distribution, and Option B has a standard deviation of 0, which would result in all probabilities being 0 or 1. Option D has a large standard deviation of 10, which would result in a very spread-out distribution and would not be suitable for calculating normal probabilities using the standard normal distribution table. Therefore, Option C is the best choice.
