The value of α = 0.26 finding by using normal distribution.
A normal distribution is an arrangement of a data set in which most values cluster in the middle of the range and the rest taper off symmetrically toward either extreme.
Given that,
confidence level = 74%
alpha = ?
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,
α = 1 - confidence level
= 1 - 0.74
α = 0.26
Hence, The value of α = 0.26.
