Question: Three specimens of high-quality concrete had compressive strength 357, 359, 413 [kg/cm 2 ], and for three specimens of ordinary concrete the values were 346,

Three specimens of high-quality concrete had compressive strength 357, 359, 413 [kg/cm²], and for three specimens of ordinary concrete the values were 346, 358, 302. Test for equality of the population means, μ₁= μ₂, against the alternative μ₁> μ₂. Assume normality and equality of variance. Choose α = 5%
