The data set saf ety .txt contains the number of recorded safety violations at a company's six plants over a 5-year period. Use graphs and summary statis tics to explore this data set, and then write a brief report summarizing your findings. Be sure to include supporting data and graphs in your summary.

1. An experiment was performed to compare the effect of pH on the adhe sive qualities of a lens coating. The test procedure for measuring adhesion is "noisy", that is, there is a large amount of test error in the measurement. For that reason, 10 samples from each formulation were made and tested. The data are given below as well as in adhesion .txt.

4.3	15.17	14.27	13.3	17.85	15.17	13.81	17.97	13.25	13.79	13.62
5.3	15.72	15.78	15.72	15.48	15.13	18.61	14.04	13.84	14.22	16.17
6.3	15.87	14.50	15.82	14.39	17.52	15.62	16.78	15.81	15.24	16.53

(a) Make side-by-side box plots for these data.

(b) Make an error-bar chart for these data.

(d) How does pH affect the adhesion of the coating?
