The feasible region for a linear programming problem is bounded by x > 0, y = 0, 2x + 3y = 12. Find the location of the maximum and minimum values of f(x, y) = 5y - X.
The maximum value of f(x, y) occurs at Select Choice
The minimum value of f(x, y) occurs at Select Choice

A. find the power of the test, when the null hypothesis assumes a population mean of mu = 450, with a population standard deviation of 156, the sample size is 5 and the true mean is 638.47 with confidence intervals of 95 b. find the power of the test, when the null hypothesis assumes a population mean of mu = 644, with a population standard deviation of 174, the sample size is 3 and the true mean is 744.04 with confidence intervals of 95% c. find the power of the test, when the null hypothesis assumes a population mean of mu = 510, with a population standard deviation of 126, the sample size is 10 and the true mean is 529.44 with confidence intervals of 95
