Bus520 Discussion Post: The Use of Z-test

Bus520 Discussion Post Student’s Name Institutional Affiliation Bus520 Discussion Post First Post Based on the hypothesis stated above, Frank’s post should have elaborated on the use of Z-test as the sample size exceeds 30. Additionally, the descriptive statistics, such as mean, standard deviation, and variance should have included sample and population mean. The two means should have a significant difference signifying they are not equal, thus satisfying the alternative hypothesis. Notably, the sample would not be a representation of the parent population. The descriptive statistics involved would be to get the exact p-value for the sample data (Ko, Hung, Chang, & Lin, 2014, p. 27). As a result, the comparison between the given level of significance 0.05 would be against the resulting p-value. In the case that the p-value exceeds 0.05, the null hypothesis would be rejected. Consequently, the method would win as Frank wishes. Second Post Based on Aaron’s post, the use of the Z-test for p...
