Part c # 4 A simple random sample of size n is drawn from a population whose population standard deviation, o, is known to be 7.3. The sample mean, x, is determined to be 53.1(a) Compute the 95% confidence interval about u if the sample size, n, is 35.A 95% confidence interval is (50.69, 55.52).(Use ascending order. Round to two decimal places as needed.)(b) Compute the 95% confidence interval about u if the sample size, n, is 50.A 95% confidence interval is (51.08 , 55.12 ).(Use ascending order. Round to two decimal places as needed.)How does increasing the sample size affect the margin of error, E?GA. As the sample size decreases, the margin of error decreases.O B. As the sample size increases, the margin of error stays the same.C. As the sample size increases, the margin of error decreases.(c) Compute the 99% confidence interval about u if the sample size, n, is 35.A 99% confidence interval is ( D.(Use ascending order. Round to two decimal places as needed.)

A dietitian in a hospital is to arrange a special diet composed of three basic foods. The diet is to include exactly 340 units of calcium, 180 units of iron, and 400 units of vitamin A The number of units per ounce of each special ingredient for each of the foods is indicated in the table. Construct a Units per Ounce Food A Food B Food C Calcium 30 10 20 Iron 10 10 20 Vitamin A mathematical model to complete parts (A) through (C) below. Use Gauss-Jordan elimination to solve the model and then interpret the solution. 30 30 Construct a mathematical model for this situation. Let the first, second, and third equations represent calcium, iron, and vitamin A, respectively. Let x, represent the number of ounces of food A, x, represent tine number of ounces of food B, and x, represent the number of ounces of food C. - 2 * 3 = X, + X, + %3D (Type integers or decimais.) 20
A company manufactures a product at its plants in A, B, and C, then ships the product to six customers in G, H, J, K, and L, The monthly capacity of plants A, B, and Care 7400, 7300, and 10000 units, respectively. The monthly demand from customers G, H, J, K, and Lare 3000, 500, 4600, 7500, and 8900 units, respectively. Use Excel Solver to find the optimal distribution plant that will give the lowest total monthly shipping cost if the shipping cost per unit (in dollars per unit) are as follows: - from A to G, H, J, K, and L are 4, 9, 20, 6, and 13 dollars per unit, respectively; from B to G, H, J, K, and L are 12, 7, 3, 10, and 6 dollars per unit, respectively; from C to G, H, J, K, and L are 7, 6, 12, 2, and 9 dollars per unit, respectively. - The optimal total shipping costs is dollars per month.
