Q1) Determine a random number generator and make simulated data for not more than 25 participants (test subjects) in study using ranges of values for variables you established above.
Q2) Using hypothesis testing methods presented in Sekaran (2003), propose a method that you think would be most suitable to test this hypothesis. Limit your choices of hypothesis testing to only one of 3 possibilities: graphical method, correlation or t-test. You may use statistical functions in MS Excel for any of these 3 methods. Ultimately, describe rationale for your selection. Why was this method selected when compared with strengths and weaknesses of other two methods?
Now that you have created "notional" (simulated) data to show the hypothesis testing method, apply these data to hypothesis testing method you selected. Based on simulated data and your hypothesis testing method, point out if the null hypothesis is accepted or rejected and why.
Based on your findings, comment on potential implications of these findings as potential contribution to scholarly literature.
