Math Problem Statement

Find the z-score that best satisfies the given condition using the Standard Normal Curve Areas table.

Solution

It looks like you've shared an image of a Standard Normal Curve (Z-score) Table. This table shows areas under the standard normal curve corresponding to different Z-scores, which is useful for finding probabilities in a normal distribution.

To find probabilities:

  1. Identify the Z-score you're interested in.
  2. Locate the Z-score in the left column and the corresponding decimal part in the top row.
  3. The value at this intersection is the cumulative probability or area under the curve to the left of that Z-score.

Would you like to know how to use this table to solve specific problems or need help finding a certain Z-score value?


Here are some related questions to expand your understanding:

  1. What does the area under the normal curve represent?
  2. How do you interpret a Z-score in terms of standard deviations?
  3. How can you use this table to find probabilities between two Z-scores?
  4. What steps are involved in converting raw scores to Z-scores?
  5. How do you handle negative Z-scores using this table?

Tip: Remember, for a standard normal distribution, about 68% of values lie within ±1 standard deviation, 95% within ±2, and 99.7% within ±3.
