Produce a side by side box plot for the percentage of bone loss in the breast feeding group vs the control group. The produce side by side histograms for the percentage of bone loss in the breast feeding group vs. the control group. Please test to see if the mean percentage of bone loss in the two groups are the same using the right version of the t test based on the SPSS output.  Calculate a 95% confidence interval for the mean difference in the percentage of bone loss between the two groups
