Question

What are the critical values for quick reference during this activity?

1) 0.90 z* = 1.645
2) 0.95 z* = 1.960
3) 0.99 z* = 2.576

Answer 1

The critical values for quick reference during this activity are 1.645, 1.960, and 2.576 for confidence levels of 0.90, 0.95, and 0.99 respectively.

Step-by-step explanation:

The critical values for quick reference during this activity are:

1. For a confidence level of 0.90, the critical value (z*) is 1.645.
2. For a confidence level of 0.95, the critical value (z*) is 1.960.
3. For a confidence level of 0.99, the critical value (z*) is 2.576.

These critical values are used in determining the boundaries of a confidence interval for a population parameter, based on the standard normal distribution.
