Please solve the exercise below in Excel and show your work (and formulas)

3. Test H0: &#956;1 &#8804; &#956;2; H1: &#956;1 > &#956;2 at &#945; = 0.05, when 1 = 75, 2 = 72, s1 = 3.3, s2 = 2.1, n1= 6, n2= 6. Assume equal variances. Indicate which test you are performing; show the hypotheses, the test statistic and the critical values and mention whether one-tailed or two-tailed.
