Find the critical value, tc, for c=0.95 and n=41.

Expert Solution

Solution:- Given that c = 0.95, n = 41
df = n-1 = 41 - 1 = 40

the critical value, tc = 2.021
Explanation:-
The following information is provided: the requested significance level is α=0.05, for the two-tailed case.
The t-critical values for a two-tailed test, for a significance level of α=0.05 are

t_c = -2.021 and t_c = 2.021
