c) Create an appropriate model.
d) Estimate the number of swings for a pendulum with a 4-inch string.
e) Estimate the number of swings for a pendulum with a 48-inch string.
f) How many confidences do you place in these predictions? Why?
Please use RStudio to solve. It appears that someone solved this problem using another software. I
was able to follow them until I got to B, then I started to have different number and scatterplot.

Use the data provided on Canvas. In automotive assembly processes, automation cannot always guarantee the dimensional accuracy of a car assembly as required by the design specification. Thus, some skillful workers will visually inspect those assembled car bodies and conduct manual adjustments when necessary. These workers are called "Fitter" in the automotive industry. This scenario is illustrated in the following figure. Automatic assembly process X P₁ Fitter Y P₂ One critical quality characteristics on a car assembly were measured at both P₁ (before fitter) and P₂ (after fitter). The data are labeled as X and Y, respectively, and 20 measurements are shown below. Please use the risk adjustment method to test if X and/or Y are in control. Please show X chart, Y chart and Z chart.
