Two labs from different universities are comparing results on a similar study to see if they are in agreement. Conduct an independent samples t-test on the following data; assume a two-tailed hypothesis witha = .05. Based on this analysis, is there a significant difference in the results between the two universities?

University A: 9 13 15 11

University B: 5 7 8 8 10 4
