Transcribed Image Text:The image is a table representing the probability values for a standard normal distribution, often referred to as a Z-table. It shows the cumulative probabilities \( P(Z < z) \) for specific Z-scores.
The columns represent the decimal part of the Z-score: 0.00, 0.01, and 0.02. The rows represent the integer and first decimal of the Z-score: 1.8, 1.9, 2.0, and 2.1.
Here's the table breakdown:
- For \( Z = 1.8 \):
- \( P(Z < 1.80) = 0.9641 \)
- \( P(Z < 1.81) = 0.9649 \)
- \( P(Z < 1.82) = 0.9656 \)
- For \( Z = 1.9 \):
- \( P(Z < 1.90) = 0.9713 \)
- \( P(Z < 1.91) = 0.9719 \)
- \( P(Z < 1.92) = 0.9726 \)
- For \( Z = 2.0 \):
- \( P(Z < 2.00) = 0.9772 \)
- \( P(Z < 2.01) = 0.9778 \)
- \( P(Z < 2.02) = 0.9783 \)
- For \( Z = 2.1 \):
- \( P(Z < 2.10) = 0.9821 \)
- \( P(Z < 2.11) = 0.9826 \)
- \( P(Z < 2.12) = 0.9830 \)
