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

step-by-step explanation:

given the function as;

write the equation replacing f(x) with y

form   and fill a table containing values of y with corresponding values of x

you can take a range for   values of x as -3≤x≤3

solving for x=-3

for x=-2

repeat the same procedure to get the values of y for the remaining ,x=-1 to x=3

plot the values of y against values   of x and obtain the following graph
