Making a decision: Numeric results for several independent-samples t tests are presented here. Decide whether each test is statistically significant and report each result in the standard APA format.

a. A total of 73 people were studied, 40 in one group and 33 in the other group. The test statistic was calculated as 2.13 for a two-tailed rest with alpha level of 0.05

b. One group of 23 people was compared to another group of 18 people. The t statistic obtained for their data was 1.77. Assume you were performing a two-tailed test with an alpha of 0.05.

c. One group of nine mice was compared to another group of six mice, using a two-tailed test at an alpha of 0.01. The test statistic was calculated as 3.02.
