Find the critical​ t-value that corresponds to 95​% confidence. Assume 20 degrees of freedom.

Find the critical​ t-value that corresponds to 95​% confidence. Assume 20 degrees of freedom.

Solutions

Expert Solution

df = 20 , 1-alpha = 0.95 , alpha = 0.05 , alpha /2 = 0.025

Critical value = tc = tdf,alpha/2  = t20,0.025 = 2.086

From table find n=20 & alpha/2 = 0.025 it is equal to 2.086
