Project 4

STA2023 Project 4 (P4)

• The P4 is the final phase of the course project in which the main topics are the inferential procedures.
• Provided that in the three previous phases the concentration was related to the data collection, the data organizing, the data display and the exploratory data analysis to provide a throughout data description in writing, where all the displays( Stem and Leaf, Box plot, Histogram, Control Chart, Normality test, Chi-square tests) are explained, as all the descriptors in the descriptive statistics panel provided in minitab 17; the phase 4 incorporates the calculation of the confidence interval and the hypothesis test for the main quantitative analysis of your case. You must formulate a reasonable hypothesis, belief or claim.
• You need to produce either two or more groups to compare ( if you have only two clear group you will run a t – test comparing the means with your comparative claim, if your data supports more than two groups you run ANOVA using the different groups , in both cases use minitab to conduct the test)
• Develop a correlation regression analysis incorporating the inferential analysis of the correlation regression tests.
• Submit the complete project document with the title, abstract, introduction, body, conclusions and bibliography including the displays and results in minitab17 embedded pated in the body of the document.
