3. Generate random values from three different normal distributions, each with a different mean and standard deviation. Pick whatever values you like, and whatever sample sizes you like. Then make a boxplot that should have the following features: a. Three boxes are plotted side by side, one for each distribution (note: boxplot(a,b,c) will plot a, b, and c next to each other). b. Each box is colored a different shade of grey 0. Each box has a meaningful label below it. You can use the \"names\" plotting argument to give each boxplot a name that identies its mean and standard deviation (e. g. \"mean=0, sd=2\"). d. The numbers on the y axis and labels on the x axis are displayed in a smaller size than R's default size. There is not a full square box drawn around the plot; only the horizontal and vertical axes are drawn with lines
