Six different settings are tried on a machine to see if any of them will reduce the proportion of defective parts. For each setting, an appropriate null hypothesis is tested to see if the proportion of defective parts has been reduced. The six P-values are 0.34, 0.27, 0.002, 0.45, 0.03, and 0.19. a) Find the Bonferroni-adjusted P-value for the setting whose P-value is 0.002. Can you conclude that this setting reduces the proportion of defective parts? Explain. b) Find the Bonferroni-adjusted P-value for the setting whose P-value is 0.03. Can you conclude that this setting reduces the proportion of defective parts? Explain.

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
