A filling machine is used to fill cartons with a liquid product. The specificationthat is strictly enforced for the machine is 9 ± 2.5 oz. If a carton produced weighsoutside these bounds, it is considered by the supplier to be defective. It is hoped thatat least 99% of cartons will meet these specifications. It is assumed that the weightfollows a normal distribution.a. With the conditions µ=9 and o=1, what proportion of cartons from the processare defective?b. If changes are made to reduce variability, what must o be reduced to in order tomeet specifications with probability 0.99?

Let X be the weight of cartons that is normally distributed with mean, μ=9 and standard deviation,…

The operations manager of a plant that manufactures tires wants to compare the actual inner diameters of two grades of tires, each of which is expected to be 575 millimeters. Samples of five tires from each grade were selected, and the results representing the inner diameters of the tires, ranked from smallest to largest, are shown below. Complete parts (a) through (c) below. Grade X Grade Y Q 567 573 577 581 584 570 574 577 579 583 a. For each of the two grades of tires, compute the mean, median, and standard deviation. The mean for Grade X is mm. (Type an integer or a decimal.) C
b) Given P = W²H.If errors up to 2% and 1% are possible in the measured value of W and H respectively, then find the percentage error in the calculated value of P.

In this problem, assume that the distribution of differences is approximately normal. Note: For degrees of freedom d.f. not in the Student's t table, use the closest d.f. that is smaller. In some situations, this choice of d.f. may increase the P-value by a small amount and therefore produce a slightly more "conservative" answer. The western United States has a number of four-lane interstate highways that cut through long tracts of wilderness. To prevent car accidents with wild animals, the highways are bordered on both sides with 12-foot-high woven wire fences. Although the fences prevent accidents, they also disturb the winter migration pattern of many animals. To compensate for this disturbance, the highways have frequent wilderness underpasses designed for exclusive use by deer, elk, and other animals. In Colorado, there is a large group of deer that spend their summer months in a region on one side of a highway and survive the winter months in a lower region on the other side. To…

To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material. Compute the values below (to 2 decimals, if necessary). Sum of Squares, Treatment Sum of Squares, Error a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use a = 0.05. Mean Squares, Treatment 0000 Mean Squares, Error Calculate the value of the test statistic (to 2 decimals). 1 17 23 21 19 What conclusion can you draw after carrying out this test? - Select your answer - Manufacturer 2 28 26 31 27 + 3 18 17 21 20 The p-value is - Select your answer - What is your conclusion? - Select your answer - b. At the a = 0.05 level of significance, use Fisher's LSD procedure to test for the equality of the means for manufacturers 1 and 3. Calculate Fisher's LSD Value (to 2 decimals).
There is a 3 percent error rate at a specii c point in a production process. If an inspector isplaced at this point, all the errors can be detected and eliminated. However, the inspectoris paid $8 per hour and can inspect units in the process at the rate of 30 per hour.If no inspector is used and defects are allowed to pass this point, there is a cost of $10per unit to correct the defect later on.Should an inspector be hired?
