when finding the margin of error for the mean of a normally distributed population from a sample, what is $alpha$, assuming a confidence level of 74%?\n0.13\n0.26\n0.74\n0.87

Answer

Explanation:

Step1: Recall the relationship between confidence level and $\alpha$

The confidence level $C$ and $\alpha$ are related by the formula $C = 1-\alpha$.

Step2: Rearrange the formula to solve for $\alpha$

We have $\alpha=1 - C$.

Step3: Convert the confidence - level percentage to a decimal

The confidence level $C = 74%=0.74$.

Step4: Calculate $\alpha$

Substitute $C = 0.74$ into the formula $\alpha = 1 - C$. So, $\alpha=1 - 0.74=0.26$.

Answer:

0.26
