Suppose you have two groups, with Group 1's sample size being 76and Group 2's sample size being 68. The average of the first groupis 31.85 and a sample standard deviation of 10.44. The average ofthe second group is 29.16 and a sample standard deviation of 11.1.Can you reject the null that there is no difference between the twogroups at the 99% significance level?
