How many degrees of freedom should the chi-square test have? B E 1
A group of students take the SAT, then take an SAT prep class, then take the SAT again. To test the null hypothesis that the prep class did not significantly improve scores for these students, which population mean would be used in our t-test? Zero The original (before) SAT score of the group The second (after) SAT score of the group The national mean SAT score
Tru or False? For a right-tailed test, reject the null hypothesis only if P < α. For a left-tailed test, reject the null hypothesis only if P < α. If we reject the null hypothesis at a significance level of α = .01, then we also reject the null hypothesis at a significance level of α = .05.
hii! can someone help me with this? thank you!!
