The following are random samples from approximately Gaussian (normal) populations:
Sample 1: 2, 0, 4, 0
Sample 2: 7, 8, 10, 9, 8, 7, 9
Determine whether there is a statistically significant difference between the two groups.
Complete a formal hypothesis test including the null and alternate hypotheses stated in symbols and words, determination of whether to use a one-tailed or a two-tailed test, the appropriate stats calculations, and a conclusion (reject or fail to reject the Ho and a statement).
