Using an independent samples t-test a researcher obtains a t-statistic of 2.316, he rejects the null at the 2 tailed alpha level of 0.05. Estimate N1+N2 (Total N, Total number of subjects): less than 8 8 or more 10 or more less than 10 7 or more

QUESTION 11 You run an independent samples t-test between two groups, and find a t-statistic of t=1.67. Is this sufficient to reject the null hypothesis? Assume α=0.05 and a one-sided test. Yes, > 1.67 is sufficient to reject the null. No, > 1.67 is not sufficient to reject the null. Not enough information. 2 points QUESTION 12 In a dependent samples t-test, the sample sizes must be equal. True False 2 points QUESTION 13 In an independent samples...
Find the critical t-value(s) for a two independent samples t-test given: α = 0.05 n1 = 12 n2 = 11 two-tailed test
two samples of n=5 subjects were analyzed with an independent -samples t-test, producing a t=2.295 does this indicate a significant difference in a two tailed test with alpha= .05?
PLEASE help ?? A researcher conducted a single sample t-test on results of an experiment with n = 18 participants and the computed t = -2.28. What is the correct conclusion from this experiment if p < 0.05, 2-tails test is used for hypothesis testing? O A. The researcher failed to reject the null hypothesis and concluded that there is a significant treatment effect. O B. The researcher rejected the null hypothesis and concluded that there is a significant treatment...
