You have just started at a company and they present you with historical data for the time in minutes that it takes to prepare A solar panel. The company has 3 locations and they give you the following sample data:

Site 1 107.55 106.2 102.96 106.74 114.21 109.8 104.49 122.85 107.55 112.23 109.53 99.18 107.1 111.33 108.45 110.25 112.41 109.71 108.63 110.16 106.74 108.45 100.44 108.54 104.58 111.15 113.76 106.65 104.4 109.89 111.15 104.04 112.32 107.37 101.79 105.12 110.7 104.22 107.37 107.28

Site 3 115.29 113.94 111.15 112.95 114.57 106.47 113.04 115.38 113.49 108.54 110.97 123.66 110.43 114.3 110.97 110.61 102.87 109.17 114.39 114.84 114.93 117.54 107.37 109.98 111.42 109.53 102.24 111.15 118.71 111.24 117.36 114.3 110.79 104.31 109.71 111.51 109.53 118.44 112.32 111.51

They are interested in characterizing the data at these three locations. The QC manager stated that their goal is 120 min or less because then they could (ideally) make 4 per 8 hour day.

1. Determine if the data are normally distributed and list the mean and standard deviation for each site. Please include all necessary graphs.
2. Using both histograms and box plots, explain how the graphical data supports the approach to the characterization of the data described in question a
