Left-Tailed Hypothesis Test A … NettetLeft-tailed: If \(H_a \) is left-tailed, then the p-value is the probability the sample data produces a value equal to or less than the observed test statistic. Right-tailed : If \(H_a \) is right-tailed, then the p -value is the probability the sample data produces a value equal to or greater than the observed test statistic.
NettetLeft-tail critical value: 1 – (0.05 / 2) = 0.975. In the chi-square table below, I highlight these two results. The chi-square table shows that our lower critical value is 0.831 and the upper critical value is 12.833. Consequently, our results are statistically significant if the χ 2 test statistic when ≤ 0.831 or ≥ 12.833. Nettet8. nov. 2024 · Table of contents. Step 1: State your null and alternate hypothesis.

A left-tailed test would state that cars traveling … NettetDepending on the alternative hypothesis operator, greater than operator will be a right tailed test, less than operator is a left tailed test, and not equal operator is a two tailed test. Alternative hypothesis has the greater than operator, right tailed test. Alternative hypothesis has the less than operator, left tailed test.
