which to reject or accept the null hypothesis. The fourth step involves running a test-get results and making decisions based on step three above. In this step, the decision on whether or not the test results are statistically significant based on the p-value is made. The last step is analyzing the results and giving insight into the problem by stating the conclusion in the setting of the original problem. In hypothesis testing, type I errors ensue when the accurate null hypothesis is rejected. This category of error can be controlled, and the value of alpha that is related to the selected level of significance has a direct pertinence on these errors (OutLieer, 2012). Conversely, type II errors arise when the wrong null hypothesis is not rejected. It arises when the null hypothesis is stated to be true when it is false. A decision outcome can be improved by reducing the type I or type II errors. Although the errors cannot be eliminated, one kind of error can be minimized when its probability is

HYPOTHESIS TESTING 3 decreased while increasing the likelihood of the other type (Gaston, 2014). The value of alpha can be reduced from 0.05 to 0.01, and this will ensure improvements in the decision outcome.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
