(d) Find the critical t-value that corresponds to
95% confidence. Assume 13 degrees of freedom.
(Round to three decimal places as needed.)
I do not understand the steps to get the right tail please show all work
Solution :
Given that ,
degrees of freedom = 13
= 1 - 95% = 1 - 0.95 = 0.05
/ 2 = 0.05 / 2 = 0.025
Using t table,
t
/2,df = t 0.025 , 13 = 2.160
t critical value = 2.160
