For the five measurements on the two variables R1, and R2, conduct both a two-sample t test (assume

σ1 = σ2, both unknown) and an ANOVA test on means. Perform two-tailed tests for

(a) Y1 = 8, Y2 = 8, and

(b) Y1 = 8, Y2 = 14 use a level of significance of 5%. Explain any difference in the results of the two tests.
