Find the critical value given a sample size of 20 with 98% confidence

Multiple choice:

a) 2.086

b) 2.539

c) 2.093

d) 2.528

Expert Solution

Given that, sample size (n) = 20

Significance level = 1 - 0.98 = 0.02

Degrees of freedom = 20 - 1 = 19

Using t-table we get, t-critical value at 0.02 level of significance with 19 degrees of freedom is,

=> Critical value = 2.539
