Suppose X ~ N(59, 4). Write the Excel function to find the X values associated with the following percentages: a. Highest 21 percent

multiple choice 1

• =NORM.INV(79,59,4)
• =NORMS.INV(0.79,59,4)
• =NORM.INV(0.79,59,4)

b. Middle 56 percent multiple choice 2

• X_upper =NORM.INV(0.22,59,4), X_lower=NORM.INV(0.79,59,4)
• X_upper =NORM.INV(0.78,59,4), X_lower=NORM.INV(0.22,59,4)
• X_upper =NORMS.INV(0.79,59,4), X_lower=NORMS.INV(0.22,59,4)

c. Lowest 23 percent multiple choice 3

• =NORM.INV(0.23,59,4)
• =NORM.INV(0.77,59,4)
• =NORMS.INV(0.23,59,4)
