Your first real R assignment (see R comments/instructions at the end):

a) Download/save the data set from the course web page (look for the link next to homework 2). These are real data on the length of snapping turtles. http://mason.gmu.edu/~alaemmer/bio214/main.html

b) Read the data into R.

c) Calculate the mean and standard deviation for the length of our turtles (both sexes combined - see also part (e)).

d) How many males are there? Females?

e) Suppose we want to know the means for females vs. males. Go ahead and calculate the mean for females and for males.

f) Repeat (e), but now do the median, standard deviation, and variance for males and females.

g) Generate a histogram of this data set.

h) Finally, make a parallel boxplot for these data (males vs. females).

please provide r script code and show all steps and boxplot
