Find each of the following. Enter your answers rounded $t$
Part 1 of 5
$z_{\alpha / 2}$ for the $95 \%$ confidence interval
\[
z_{\alpha / 2}=\square
\]
Answer
Final Answer: The z-score for a 95% confidence interval is approximately \( \boxed{1.96} \).
Step 1 ：The question is asking for the z-score for a 95% confidence interval. The z-score is a measure of how many standard deviations an element is from the mean.
Step 2 ：In a normal distribution, a 95% confidence interval corresponds to a z-score of approximately 1.96. This is because 95% of the data in a normal distribution is within 1.96 standard deviations of the mean.
Step 3 ：Therefore, we can calculate this directly.
Step 4 ：Final Answer: The z-score for a 95% confidence interval is approximately \( \boxed{1.96} \).
