# Homework 0 for Statistics 101-106 (Fall 98)

Due: Thursday 10 September

(0.1) Use Minitab to produce a picture that would help a student to decide whether to drop the course (or not) after seeing only the results from the midterm and the first 6 homework sheets.

(0.2) Produce a picture that shows how well the results from the midterm and the first 6 homework sheets predict the final class rank. (How should you combine homework, midterm, and final to determine relative standing?)

This sheet refers to the Yale grades data set:

```
The following data consist of the scores for students in a particular
Yale course on 11 homework sheets (columns headed S1 through S11), the
midterm, and the final exam.  The last row gives the scores for a
hypothetical perfect student, that is, it gives the maximum score
possible.

A score of zero always indicates that a student failed to hand in a
homework sheet.

The combined homeworks (with midterm score added in) counted for 50% of the grade;
the final exam counted for the other 50%.

The items within each row are separated by a single tab character.
