Dwayne and alisha both correctly graphed a standard normal curve. which of the following statements is true? neither the means nor the standard deviations of dwayne’s and alisha’s graphs must be the same. the means of dwayne’s and alisha’s graphs must be the same but not the standard deviations. the standard deviations of dwayne’s and alisha’s graphs must be the same but not the means. both the means and the standard deviations of dwayne’s and alisha’s graphs must be the same.

The correct answer is "Both the means and the standard deviation of Dwayne's and Alisha's graphs must be the same."

Explanation:

By definition, the standard normal distribution is a special case of a normal distribution. It is the distribution that occurs when a normal random variable has a mean of 0 and a standard deviation of 1. Because of this the means and the standard deviation of Dwayne's and Alisha's graphs must be the same.

d: both the graphs must be the same

b. they are parallel and will never intersect.

fist on the left goes with the third on the right. second on the left goes with the fourth on the right. third on the left goes with the second on the right. the fourth on the left goes with first on the right
