More about cicadas. Lets examine the distribution of seed mass for plants inthe cicada group of Exercise 7.9 in more detail.(a) Make a stemplot. Is the overall shape roughly symmetric or clearly skewed?There are both low and high observations that we might call outliers.(b) Find the mean and standard deviation of the seed masses. Then remove boththe smallest and largest masses and find the mean and standard deviation ofthe remaining 37 seeds. Why does removing these two observations reduce s?Why does it have little effect on x?
