6. One sample of fifteen observations has x₁ = 82 and s₁ = 5. A second sample of ten observations taken by a different scientist has x₂ = 88 and s₂ = 7. Is there a significant difference between the two sample means at the (a) 0-05 and (b) 0.01 level of significance? (You may assume that the two populations have equal variances.)
