D Question 4 1 pts The 'n' in the mean difference formula for this chapter represents O the difference between the two samples sires. O the number of participants in the study. O the number of difference scores. O the sum of the n for both groups. D Question 5 1 pts The smaller the sample size, the larger the denominator of t. which leads to that is to land in a critical region and produce a significant mean difference. O a smaller t-statistic; less likely O a bigger t-statistic: more likely O a smaller t-statistic: more likely O a bigger t-statistic: less likely Question 6 1 pts It is to pick up on differences when the variability of scores is O harder; low O harder, unknown O easier; low O easier: highD Question 4 1 pts The 'n' in the mean difference formula for this chapter represents O the difference between the two samples sires.
