A categorical response variable showed three options: the company plans tohire and add to the number of employees, the company plans no change in the number of employees, or the company plans to lay off and reduce the number of employees. Another categorical variable indicated if the company wasprivate or public. Sample data for 180 companies are summarized as follows.Employment PlanAdd EmployeesNo ChangeLay Off EmployeesCompanyPrivate Public371916323442(a) Conduct a test of independence to determine if the employment plan for the next 12 months is independent of the type of company.State the null and alternative hypotheses.O Ho: Employment plan is not independent of the type of company.H₂: Employment plan is independent of the type of company.O Ho: Employment plan is independent of the type of company.H₂: Employment plan is not independent of the type of company.O Ho: Employment plan is not mutually exclusive from the type of company.H₂:: Employment plan is mutually exclusive from the type of company.O Ho: Employment plan is mutually exclusive from the type of company.H₂: Employment plan is not mutually exclusive from the type of company.Find the value of the test statistic.
