Final answer:
To find the area between the mean and a specific z-score, we need to use the z-table. The area between the mean and the z-score of 1.23 is 0.1093.
Step-by-step explanation:
To find the area between the mean and a specific z-score, we need to use the z-table. First, locate the z-score in the table, which corresponds to an area under the normal curve to the left of the z-score. In this case, the z-score is 1.23. The area to the left of this z-score is approximately 0.8907. Next, subtract this area from 0.5 to get the area between the mean and the z-score. So, the area between the mean and the z-score 1.23 is 0.5 - 0.8907 = 0.1093.
