Question

When conducting a t test for independent means,

A. the medians of the two populations are assumed to be equal.
B. the null hypothesis is rejected if the t score you compute is more extreme than the cutoff t score.
C. only the .01 significance level should be used because of the greater power compared to a t test for dependent means.
D. all of the above.
One of the assumptions for the t test for independent means is that

A. sample means are not significantly different.
B. the mean of the distribution of differences between means is 1.
C. the variance of each of the parent populations is the same.
D. the means of each of the parent populations vary by no more than 1 standard deviation.
If a research article reports a result as "t(28) = 4.21, p < .01."

A. the result was statistically significant.
B. there were 30 subjects in the study.
C. the t score was 4.21.
D. all of the above.
Which of the following is an example of the most common way for a t test for independent means to be reported in a research article?

A. t(i:29) < .05
B. independent t(15): 30.16, p: significant
C. t(independent) = 2.93, significant
D. t(45) = 3.52, p < .05
A. the medians of the two populations are assumed to be equal.
B. the null hypothesis is rejected if the t score you compute is more extreme than the cutoff t score.
C. only the .01 significance level should be used because of the greater power compared to a t test for dependent means.
D. all of the above.
