The area to the left of z is 1-0.1112=0.8888. Using a standard normal distribution table or calculator, we can find the corresponding z-value to this area, which is approximately 1.22. Therefore, the value of z such that the area to the right of it is 0.1112 is -1.22 (since we want the area to the right of z, not the left).
