Find the critical value, t 0 t0, to test the claim that mu 1 μ1 not equals ≠ mu 2 μ2. Two samples are randomly selected and come from populations that are normal. The sample statistics are given below. Assume that sigma Subscript 1 Superscript 2 σ21 not equals ≠ sigma Subscript 2 Superscript 2 σ22. Use alpha equals 0.02 . Use α=0.02. n 1 n1 equals =11, n 2 n2 equals =18, x overbar 1 x1 equals = 8.6 8.6, x overbar 2 x2 equals = 9 9, s 1 s1 equals =0.76, s 2 s2 equals =0.51

To construct a confidence interval for the difference between two population means mu 1 minus mu 2, use the formula shown below when both population standard deviations are known, and either both populations are normally distributed or both n 1 greater than or equals 30 and n 2 greater than or equals 30. Also, the samples must be randomly selected and independent. left parenthesis x overbar 1 minus x overbar 2 right parenthesis minus z Subscript c Baseline StartRoot StartFraction...
