Given the null hypothesis is true, a p-value is the probability of getting a result as or more extreme than the sample result by random chance alone. If a p-value is lower than our significance level, we reject the null hypothesis. WebIt is the opposite of your research hypothesis.

WebStatistics A hypothesis test is to be performed for a population mean with null hypothesis of H0: u=u0 . The test statistic used will be z= x - u0 / o / square root of n.. Find the critical value (s) for a two-tailed test with α = 0.02 and draw a graph that illustrates your answer. WebA null hypothesis is rejected when the P-value is less than the level of significance, α. Therefore, if the null hypothesis would be rejected with a level of significance of α , then the P-value is less than α. In this problem, since the null hypothesis is rejected, the P-value is less than α = 0.05.
