      Thus, with a Z value of 2.46, the p-value = .0069. We reject H0 at the .05 level and say that there is a less than 1% chance of getting a x of 450 or more extreme. Conclusion: A Z value of 2.46 indicates that our sample mean is in the critical region and this is a very unlikely outcome if H0 is true and, thus, the decision to reject H0.

      Calculation of P-Values Suppose we are doing a two–tailed test: • Null hypothesis: = 0 • Alternative hypothesis: ̸= 0 • Give the null hypothesis the benefit of the doubt and assume that it is still the case that = 0. • Now calculate the P–value which is the smallest probability for which we would have rejected the null hypothesis. X. • In terms of the z–distribution (or t ...
