QUESTION 3 A researcher analyzed the pre- and post-intervention scores of a groups of students in a research study. A dependent measures t-test revealed a significant effect of the intervention. What was his outcome? O "t(34) = 3.75, p = .02" O "t(34) = 0.29, p = .67" O "r= .65, p = .002" O "t(34) = 2.35, p = .07" QUESTION 4 "A research report describing the results from a independent t-test included the following statement: t(8) = 2.78, p = .04. Based on this report, using a standard alpha level, is this effect statistically significant?" O "no, because p must be less than .001 to be statistically significant" O "yes, because p must be less than .001 to be statistically significant" O "no, because p must be less than .05 to be statistically significant" O "yes, because p must be less than .05 to be statistically significant"
