Answer #1

Using t

(a)    

t(30) = 3.330

P-value = 2 * P(t 30 > 3.330) = 0.0023

Yes, the test is significant.

(b)    

t(15) = 2.541

P-value = 2 * P(t 15 > 2.541) = 0.0226

Yes, the test is significant.


(c)    

t(14) = 2.032

P-value = 2 * P(t 14 > 2.032) = 0.0616

No, the test is not significant.     
(d)    

t(60) = 1.951

P-value = 2 * P(t 60 > 1.951) = 0.0557

No, the test is not significant.

A researcher conducts two t tests. Test 1 is a one-tailed test with a smaller sample size at a .05 level of significance. Test 2 is a one-tailed test with a larger sample size at a .05 level of significance. What do you know about the critical values for each test?

For each of the following two-samples t-tests (problems 1-6): (a) Determine if a F test for the ratio of two variances is appropriate to calculate for the context. If it is appropriate, conduct the analysis and report the result. Include what statistical conclusion you should draw from the analysis (i.e., whether you should conduct a pooled-variance t-test or an unequal-variances t-test). (b) Identify the most appropriate t-test to conduct for the situation/data given. Don’t forget to consider if the context...
