What is the critical value from Appendix B for the previous question? (Rounded to 2 places)
PREVIOUS QUESTION: Using Excel or R, what is the probability of Type I Error for an observed t-value of 2.98, df=8, alpha = 0.05, and a 2-tailed test? Give answer to 4 places.
(Behavioral Statistics) :)
t-value of 2.98, df=8, alpha = 0.05, and a 2-tailed test.
Here we want to find the critical value for the two-tailed t-test.
So we will find the critical value as tdf,alpha/2
df= 8 , alpha/2 = 0.05/2= 0.025
t8,0.025 = 2.306
So critical value for two tailed test is = -2.306 & 2.306
