When finding the margin of error for the mean of a normally distributed population from a sample, what is (photo below) , assuming a confidence level of 74%? a.) 0.13 b.) 0.26 c.) 0.74 d.) 0.87

Step-by-step explanation:

The significance level α is the probability of making the wrong decision when the null hypothesis is true. Alpha levels which is also called as significance levels are used in hypothesis tests.

Mathematically, the value of α is determined by subtracting the level of confidence from 1, and then writing the result as a decimal.

As the confidence level is given as 74%, so the significance level would be,
