Question

What is the value of α that corresponds to a level of confidence of 88%?

Question options:

	0.88
	0.12
	None of these
	12
	1.2

Answer 1

Solution:

Given, level of confidence = 88% = (1- α )100%

The significance level=  α  

Now,    (1- α )100=88

   1- α= 88/100

   1-α =0.88

   α=1-0.88

   α=0.12

Hence, the correct option is α=0.12
