The image you uploaded shows a normal distribution curve with two shaded regions. The values indicated on the horizontal axis are -0.11 and 0.98, and the question asks for the area of the shaded region under the curve.

In this case, the goal is to find the cumulative probability between the z-scores -0.11 and 0.98. This is commonly solved using a standard normal distribution table or a cumulative distribution function (CDF).

Let’s calculate the area of the shaded region by finding the cumulative probability for both z-scores:

1. The cumulative probability for \( z = -0.11 \)
2. The cumulative probability for \( z = 0.98 \)
3. Subtract the cumulative probability at \( z = -0.11 \) from that at \( z = 0.98 \) to get the area of the shaded region.

Let me calculate this.The area of the shaded region between the z-scores -0.11 and 0.98 is approximately 0.380.

5. How does the cumulative distribution function (CDF) work?

**Tip:** When dealing with normal distributions, always check if the curve follows the standard normal distribution (mean = 0, standard deviation = 1).
