• ## Null Hypothesis Case Study

Question 1 Null hypothesis The null hypothesis, which is symbolically expressed as H0, is a statement that indicates no difference between a parameter and a specific value or between two parameters. Alternative Hypothesis The alternative hypothesis, which is symbolically expressed as HA or H1, is a statement that indicates the presence of a difference between a parameter and a specific value or between two parameters.

were written correctly. For a majority of tests there were two raters, and we found between the two raters scoring “The Sun” was in agreement 97% of the time and “Sea Otters” was in agreement 94% of the time. Our first hypothesis was that recall for the study/study condition will be higher than for the study/test condition for the five minute delay. Our second hypothesis was that recall for the study/test condition should be higher than for the study/study condition for the two day delay. The…

The team’s null hypotheses or (HO) is that Hispanic pay is greater than or equal to \$30,000. The team’s alternative hypothesis or (H1) is that Hispanic pay is less than \$30,000. The significance level has been set at .05 or 95%. The z score of .05 is -1.645. If the z-value is less than -1.645 then the team can reject the null hypothesis and accept the alternative hypothesis. If the z-value is greater than -1.645 then the team fails to reject the null hypothesis, meaning Hispanic workers do, in…

• ## Consequences Of Regression Regression

Then run a regression model using the residuals square as the dependent variable and fits square as independent variable. The regression will produce a p-value for the fits square, which will be compared to the selected alpha level (it could be 1%, 5%, or 10%). If the p-value is less than the alpha level, we reject the null hypothesis in favor of the alternate. Therefore, the residuals are heteroscedastic. However, if the p-value is greater than the alpha level, we accept the null hypothesis…

sample data of 50 credit customers was collected. The manager at the store has speculated some information about credit customers. By using the sample data of 50 credit customers, along with hypothesis testing and confidence intervals, we could determine whether manager’s speculations are convincing.

supporting FEP adoption. CII has published data analysis for FEP data which analyses the relationship between project PDRI scores and scope definition, and project cost, schedule and change performance. Even though the it is evident that projects that use FEP have seen considerable performance improvements, a direct correlation between the extent of effort in FEP during the early phases of the project and the project performance have yet to be investigated. Moreover, there is a gap in the…

• ## Cowles And Davis 2006

The first criticism stated was, NHST does not provide the information the researchers are looking for (Kirk, 1996). NHST provides the probability that the researchers will obtain certain data if the null hypothesis is true; however, researchers want to know the probability the null hypothesis is true given the data they collected (Kirk, 1996). Kirk (1996) emphasized due to this confusion, researchers often make incorrect assumptions regarding the p value. He stated the utilization of NHST…
