Question 139471: need help with these problems.
a. What is the F critical value to be used at the 0.05 level of significance with 7 numerator degrees of freedom and 12 denominator degrees of freedom?
b. What is the chi-square critical value with 12 degrees of freedom for a 0.05 probability?
c. What is the exact probability of a value that fits a chi-square distribution with 17 degrees of freedom being higher than 30.995?
d. I have a sample of 13 units and I want to run a hypothesis test comparing the average to a set value. The hypothesis test uses an alpha of 0.05. What critical value would be used to compare the test statistic against?
You can put this solution on YOUR website! a. What is the F critical value to be used at the 0.05 level of significance with 7 numerator degrees of freedom and 12 denominator degrees of freedom?
3.5747
You can find these values by using Google; look for statistics F distribution
-------------------------------
b. What is the chi-square critical value with 12 degrees of freedom for a 0.05 probability?
You didn't say if it is a one tail or two tail test.
If 2-tail you get 4.4004 and 23.337
If 1-tail you get either 5.226 or 21.026
-------------------------------------
c. What is the exact probability of a value that fits a chi-square distribution with 17 degrees of freedom being higher than 30.995?0
Ch-Sq(30.995,100,17) = 0.01999...
-------------------------
d. I have a sample of 13 units and I want to run a hypothesis test comparing the average to a set value. The hypothesis test uses an alpha of 0.05. What critical value would be used to compare the test statistic against?
---------------
Ho: u = set value
Ha: u is not equal to set value
Crit value for 2-tail test with alpha = 5% and df = 12: t = +/- 2.179
