Suppose X ~ N(51, 3). Write the Excel function to find the X values associated with the following percentages:

a. Highest 24 percent multiple choice 1 =NORMS.INV(0.76,51,3) =NORM.INV(0.76,51,3) =NORM.INV(76,51,3)

b. Middle 58 percent multiple choice 2

Xupper =NORMS.INV(0.21,51,3), Xlower =NORMS.INV(0.76,51,3)

Xupper =NORM.INV(0.76,51,3), Xlower =NORM.INV(0.21,51,3)

Xupper =NORM.INV(0.79,51,3), Xlower =NORM.INV(0.21,51,3)

c. Lowest 18 percent multiple choice 3

=NORM.INV(0.18,51,3) =

NORMS.INV(0.82,51,3) =

NORM.INV(0.18,51,3)
