Assignment 4

 Hello Class,

For Assignment 4, I began by entering the data into Excel and saving as a csv file.

I then created a boxplot of the data comparing the Blood pressure of individuals given high or low final decisions (see plot below).  I used the ggplot package to do this

After that I created a histogram of Blood Pressures using the ggplot package (see plot below).

Finally I calculated the mean BP by the final decision with the following result: 

  Group.1        x
1    high 125.6667
2     low  68.0000
