In its standardized form,the normal distribution
A)has a mean of 0 and a standard deviation of 1.
B)has a mean of 1 and a variance of 0.
C)has an area equal to 0.5.
D)cannot be used to approximate discrete probability distributions.

Question

Quizplus · Accepted Answer

The standardized normal distribution has a mean of 0 and a standard deviation of 1, which allows for easy comparison and calculation of probabilities. Choice B is incorrect because the mean of the standardized normal distribution is 0, not 1. Choice C is incorrect because the area under any continuous probability distribution must be equal to 1, not 0.5. Choice D is incorrect because the normal distribution can be used to approximate many discrete probability distributions by using the continuity correction.
