Discuss the influence of: (a) the two mean values; (b) the two standard deviations; and (c) the number of data points for each data set in the statistical analysis that seeks to determine if two mean values from two different populations are statistically equivalent (or not). Assume the same level of significance (p = 0.05) for your discussion.
