Atextile engineer is interested whether the variation in breaking strength of yarn type a is larger than the variation in type b. random samples of na = nb = 7 measurements were obtained, and the sample variances were s 2 a = 5.0 and s 2 b = 1.25. assuming the two types are normally distributed, do the data provide sufficient evidence to conclude σ 2 a > σ2 b ? infer by using α = 0.05.
