State whether each of the following related samples t tests is significant for a two-tailed test at a .05 level of significance. NOTE1: You will need to use the degrees of freedom in parenthesis to look up the critical values in the t distribution table. NOTE2: If Reject H0, the t test is significant (i.e., there is a significant difference). If Retain H0, the t test is not significance (i.e., there is not a significant difference). 23 [a] t(30) = 3.220 Critical values are +/- (3 decimal places) ____________ a. Reject H0 - significant b. Retain H0 - not significant 23 [b] t(12) = 2.346 Critical values are +/- (3 decimal places
23. State whether each of the following related samples t tests is significant for a two-tailed test at a .05 level of significance.
NOTE1: You will need to use the degrees of freedom in parenthesis to look up the critical values in the t distribution table. NOTE2: If Reject H0, the t test is significant (i.e., there is a significant difference). If Retain H0, the t test is not significance (i.e., there is not a significant difference).
23 [a] t(30) = 3.220
Critical values are +/- (3 decimal places)
____________
a. Reject H0 - significant
b. Retain H0 - not significant
23 [b] t(12) = 2.346
Critical values are +/- (3 decimal places)
___________
23 [c] t(18) = 2.034
Critical values are +/- (3 decimal places)
____________
a. Reject H0 - significant
b. Retain H0 - not significant
23 [d] t(60) = 1.985
Critical values are +/- (3 decimal places)
_________
a. Reject H0 - significant
b. Retain H0 - not significant
