1. 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).

Machine1 : 35, 20, 40, 30, 25 . Machine2 : 25, 23, 20, 24, 18. Machine3 : 40, 45, 26, 34, 45 . Machine4 : 20, 34, 34, 20, 32.

NOTE: use all the steps and asnwers its my assignment and very important i need all the steps and asnwers.

2. We have consumption (Y) and their savings (X) and amount of credits . Data is given below. Please estimate the regression model for the variables by using normal equations and showing all calculation steps clearly in the Ms World file. (25p). Also interpret the coefficients (10p) You have to use the same steps which we used in the lecture.

Consumption : 140, 155,159, 179 ,192, 200 ,212, 215 . SAVNGS: 30, 62 ,67 ,70 ,71 ,72 ,75 ,78. CREDTS: 22, 25 ,24, 20 ,15 ,14 , 14, 11.

NOTE: use all the steps and asnwers.

3. In one of the faculty; students come from four different departments. They are watching four different TV series. The dean claim that there is a relationship between department and TV series. Test this claim with 0.05 significance level by using the correct test and showing each calculations step in Ms Word file.
