To find the area under a normal curve to the left of a z-score of 1.23, we can refer to the standard normal distribution table or use a calculator that provides cumulative probabilities for the standard normal distribution.

The area to the left of a z-score of 1.23 is approximately 0.8907. To express this as a percentage, you multiply by 100:
