Suppose two independent random samples of sizes n1 = 9 and n2 = 7 that have been taken from two normally distributed populations having variances σ21 and σ22 give sample variances of s12 = 11 and s22= 107.a) TestH0: σ21= σ22versusHa: σ21≠ σ22withα= 0.05. What do you conclude?(Round youranswers to 2 decimal places.)b) TestH0: σ21 ≥ σ22versusHa: σ21< σ22withα= 0.05. What do you conclude?(Round youranswers to 2 decimal places.)
