Question: 146 Time taken to solve a math programming problem. IEEE Transactions Ran a study of a new hybrid algorithm for solving polynomial 0/1 mathematical programs

146 Time taken to solve a math programming problem. IEEE Transactions Ran a study of a new hybrid algorithm for solving polynomial 0/1 mathematical programs (Data on solution times are saved in the MATHCPU file.) A SAS printout giving descriptive statistics for the sample of 52 solution times is reproduced at the bottom of the page. Use this information to determine whether the variance of the solution times differs from 2. Use a = .05.
