Answer

Brief Explanations:

A standard - normal curve has a mean of 0 and a standard deviation of 1. Since both Dwayne and Alisha correctly graphed a standard - normal curve, they must have the same mean (0) and the same standard deviation (1).

Answer:

Both the means and the standard deviations of Dwayne’s and Alisha’s graphs must be the same.
