Midterm Exam Review
MATH 4830, Spring 2006

Thrusday March 16: In-class Midterm Exam,
You may use:
1 sheet (8 1/2 x 11) two-side of notes
Calculator
Tables for critical values will be provided

For a review, we will examine two datasets: Bumpus's Data and Darwin Data

1. Bumpus's Data on Natural Selection: p. 29 is a description of the data.

(a) Using, R, you should be able to reproduce the Summary of Statistical Findings on p. 29-30.
There are also Conceptual Exercises on p.50 about this dataset (and answers).

You may read in the data from the the class web page by: 

> bump <- read.csv("http://www-math.cudenver.edu/~bbailey/4830/bumpus.csv")
> bumpus <- list(P=bump$HUMERUS[bump$STATUS=="PERISHED"],S=bump$HUMERUS[bump$STATUS=="SURVIVED"])
> bumpus
$P

$S

(b) p. 107 Problem 19: Using the R wilcox.test function

2. p. 107, Problem 28, Darwin Data: By hand (except histograms).
The data is on p. 108 or can be found off the class web page (just in case you want to check your answers!) by 

> darwin <- read.csv("http://www-math.cudenver.edu/~bbailey/4830/darwin.csv")

3. Also, look over all homework and Chapter 18.1-18.2 on Comparison of Proportions.
