Likelihood Ratio Chi-Square = 10.435, DF = 4, P-Value = 0.034. Minitab provides the (2 statistic, the number of degrees of freedom, and the P-value. The number of degrees of freedom for the (2 statistic is equal to The Minitab outputs shows that the (2 value is equal to 11.725, the degrees of freedom is equal to 4, and the P-value is equal to 0.02.

Let our test statistic be t = 1.95 and n = 36, so df = 35. The value would be the area to the right of t = 1.95. Notice the p-value is .0296. We can find this directly by typing in tcdf(1.95, 10, 35) Two –tailed test (H1: μ ≠ some number): Do the same as with a right tailed or left-tailed test but multiply your answer by 2. …
