WebTo test a hypothesis various statistical test like Z-test, Student’s t-test, F test (like ANOVA), Chi square test were identified. In testing the mean of a population or comparing the means from two continuous populations, the z-test and t-test were used, while the F test is used for comparing more than two means and equality of variance. The WebFor this data, the Pearson chi-square statistic is 11.788 (p-value = 0.019) and the likelihood ratio chi-square statistic is 11.816 (p-value = 0.019). Both p-values are less than the significance level of 0.05. Thus, the engineer concludes that the variables are associated and that the performance of the presses varies depending on the shift.
