Question
### Critical Value Determination **Problem Statement:** Find \( z_{0.91} \) (the critical value for a 91% level of confidence). Round the answer to two decimal places. There must be two digits after the decimal point. **Solution:** - This question seeks the z-value corresponding to a 91% confidence level. - Typically, this involves finding the point on the Z-distribution where the area under the curve to the right of the z-value equals \((1 - 0.91)/2\) or 0.045. **Instructions:** 1. Use a Z-table or statistical software to find the critical z-value. 2. Ensure to round your answer to precisely two decimal places. **Example:** If consulting a Z-table gives you a raw z-value, ensure to format it correctly as specified (e.g., 1.34). **Note:** This critical z-value is crucial for hypothesis testing and constructing confidence intervals in statistics.
