Dasani has two machines at a particular plant that are used for filling their plastic water bottles (nominalvolume 16 ounces). The quality engineering department tells the plant manager that both machines fill tothe same net volume (whether or not this volume averages 16.0 ounces). A random sample is taken fromthe output of the each machine.Table 1-Measured volume of water per bottle (fluid ounces)Machine 1Machine 216.0316.0116.0216.0316.0415.9615.9716.0416.0515.9815.9616.0216.0516.0216.0116.0116.0215.9915.9916.00Do you think the quality engineering department is correct?

Answer and show complete solution. Pls don't rejectIn a study on the settlement of piles used in building foundations, data on the observed pile settlement were collected and compared with the calculated/estimated values. The ratio of the observed to the calculated settlements is a measure of the accuracy of the calculation method. The ratios are shown in the table below and as can be observed, it shows considerable variability: Ratios of Observed Settlement to Calculated Settlement of Piles 0.12 0.97 0.86 1.14 0.94 2.37 0.88 0.92 1.01 0.99 1.02 1.04 0.99 0.87 0.52 0.94 1.06 1.38 1.04 1.18 1 0.86 0.82 0.84 1.09 a. Assuming that the ratio is a normal random variable, construct a probability plot and observe if the data points follow a linear trend.

A manufacturing company glues one part to another part during the assembly of its final product. Either too much or too little glue presents a problem. It is important for the pressure of the glue nozzle (pounds per square inch) to be set correctly because it affects the amount of glue (ounces) that is applied. Ten applications are sampled and the following information collected: SSXX = 129.6 SSYY = 2.345 SSXY = 16.6 X bar = 25.2 Y bar = 2.05 What is the estimated y intercept?
