It is not practical to have you create these bell curves online for me to see how you are finding your results, but you still need to do them! If you do NOT do this, the probability of making errors increases dramatically! Check your solutions manual for examples. Z score Area and Percent z < 2.22 0.9861, 98.61% z > 2.22 .0139 1/39% 0<z<2.22 1 100% Paste your answer here: (3 points) 1
