INSTRUCTION: Set up a new program of equality constraints and obtain a simplex solution tothe following linear programming problem. Write your answers in a clean sheet of paper andupload it in the google classroom.A refinery operating in Nebraska uses four crude oils: Oklahoma, Texas, Wyoming, andPennsylvania. These crudes have different delivered prices as indicated below. The refinerymakes four basic end products: regular gasoline, high-test gasoline, diesel fuel, and fuel oil. Thecatalytic cracking and characteristics of the refinery dictate a limited and different product mixfor different crudes. Data are as follows:DeliveredOptimal Through Put for each Crudeprice pergallon(pesos)CrudeRegulargasolineHigh-testgasolineDiesel fuelFuel oil30%20%10%10%20%10%Oklahoma740%Техas60%WyomingPennsylvaniaRequirements Gallons510%30%60%30%50%20%2,0001,5002,8003,300Requirement:1) Tabulate the problem in a simplex matrix with the objective of minimizing crude prices.

6. Setup: JP was curious about the sodium content of organic cornflakes. To investigate this, twenty 300-gram boxes of organic cornflakes were obtained and the sodium content was measured. The data (in milligrams) are as follows: 131.1, 130.7, 130.9, 129.5, 129.6, 128.8, 130.7, 128.3, 128.2, 129.7, 130.1, 129.3, 128.7, 129.0, 129.4, 130.4, 129.5, 130.1, 129.8, 130.0 Task: Perform a hypothesis test using R to determine if you can support a claim that the mean sodium content of this brand of cornflakes differs from 130 milligrams? Use a = 0.08 to make your decision. R Output: Upon running your analysis in R, you obtain the following results: One Sample t-test data: corn = 0.1121 t = -1.6659, df = alternative hypothesis: true mean is not equal to 130 19, р-value 92 percent confidence interval: 129.3458 130.0342 sample estimates: mean of x 129.69 Questions: (a) State the hypotheses used in performing this test.
