Left-tailed test (H1: σ < some number) Let our test statistic be χ2 =9.34 with n = 27 so df = 26. The p-value would be the area to the left of the test statistic or to the left of

We can’t just say that the estimated σˆ is sometimes 20% smaller than the true value, and sometimes 20% larger, so it all cancels out. It doesn’t, because σ doesn’t have a symmetrical distribution, but something derived from a chi-square distribution (which wehave not introduced yet). Conﬁdence intervals, ttests, P values – p.16/31

observed value. To get a p-value we compare our observed test-statistic to the randomization distribution of test-statistics obtained by assuming the null is true. The p-value will be the proportion of test-statistics in the randomization distribution that are as or more extreme than the observed test-statistic.

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 ...
