Answer:

The area lies to the right of the z-score 0.48 means all the values greater than it. This can be calculated on a graphing calculator using the function normCdf, where

Lower bound = 0.48
Upper bound = 9999
Mean = 0
Standard deviation = 1

The result would be normCdf(0.48,9999,0,1) ≈ 0.315614

The area lies to the left of the z-score 0.79 means all the values less than it. This can be calculated on a graphing calculator using the function normCdf, where

Lower bound = -9999
Upper bound = 0.79
Mean = 0
Standard deviation = 1

The result would be normCdf(-9999,0.79,0,1) ≈ 0.785236
