You work for a company that makes high end boat covers.These covers are secured to the boat using a male and female brass grommet.The male is fastened to the boat while the female is secured in the cover.The fit between these is very important for the proper installation and for keeping the grommets closed under normal working conditions.An Excel file titled Grommets-2019 can be found in the exam section of Moodle.This data is for measurements of the outside diameter of the male grommet.The size range for the grommets is 0.3711 to 0.3745 inches.You are tasked to perform a statistical analysis on the parts.

The Excel file also contains charts if you wish to use them or you can construct your own.Use the chart spacing so you get the most out of the ranges provided. For the purpose of your experiment you can eliminate any out of specification or out of control charts.This may take more than one chart.
