Aresearcher conducts a hypothesis test on a population proportion. her null and alternative hypothesis are h0 : p = 0.4 and ha : p < 0.4 . the test statistic and p-value for the test are z = −3.01 and p−value = 0.0013 . for a significance level of α = 0.05 , choose the correct conclusion regarding the null hypothesis.

The null hypothesis is not true for these values

Step-by-step explanation: The null hypothesis as described by the established p-values correspond to non-significant variables, that is, p = 0.4 (higher than the significance level). Since the result is p-value = 0.0013, the results reveal that there is statistical significance p-value <0.4, and therefore, the alternative hypothesis is true.
