There are four different machines to produce one of the products. You claim that that the weights of the products in the different machine is different. The machines need justification.
You randomly select five products from each machine from trials on an automated driving
machine. At the 0.05 significance level, is there a difference among machines in the mean
weight of the product? Test this claim showing all calculation steps clearly in the Ms. World
file (25P) and draw an ANOVA Table for the solution (10P).

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
