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
