2- When engineers working in the public and private sectors are compared in terms of income distributions, it is claimed that the income distribution of engineers working in the private sector is more heterogeneous than those in the public sector. The annual average incomes of 8 engineers randomly selected from the public and 6 from the private sector were determined. These values are given in the table below. Public 60 90 75 80 60 50 55 50 Private 260 140 90 40 40 30 Can it be said that the variance regarding the income of engineers working in the private sector at the 0.95 confidence interval is more heterogeneous than the variance regarding the income of engineers working in the public sector?
