Question

A. By looking at the variables in Employee turnover Excel file, propose one multivariant hypothesis and one simple and single hypothesis. Your hypotheses must reflect the influence of independent variable(s) on a dependent variable. In each hypothesis:

• Indicate independent variable(s).
• Indicate the dependent variable.

Discuss why you think this hypothesis is valid.

B. Conduct significance tests in R for both hypotheses at a confidence level of 90%.
