T value t = (71-7₂) √2+2 Scientists collected data on two groups of organisms. The mean, x, equals 15 for the first group and 7 for the second group. In each group, the sample variance, s2, equals 3. The sample size, n, for the first group is 10 and for the second group is is 11. Calculate the t-value for these two groups of organisms. Then, explain the next two steps that are needed to determine if this t value is statistically significant.
