These quantify the morphologic variation of the iris flower in its three species, all measurements given in centimeters. use (a) Draw the histogram of the distribution of the petal length of the iris flower: breaks=seq(0,8,1=17) to set the spacing of the bins. (i) Modify the title of the histogram and the labels of x- and y-axes to make the histogram more informative. (ii) What is the shape of the distribution of petal length of the iris flowers in the sample? (iii) What percentage of the iris flowers in the sample have a petal length of less than or equal to 2cm? (b) Draw individual histograms of the distribution of petal length for each plant species: use breaks=seq(0,8,1=17) to set the spacing of the bins. (i) Modify the titles of the histograms and the labels of x- and y-axes to make the histograms more informative. (ii) What is the most striking difference between the three distributions? (iii) Based on the histograms, which plant species has the least variability in its petal length? Explain your reasoning. Verify your claim using the appropriate R function
