The bad news is, that the textbook won't arrive in the book
store until next week.
The good news are, that I will provide copies of the first
chapter we cover on Wednesday OR as a fellow student of yours
wrote me : "Hi Professor Brose, I don't know if this might
be of help to other students in the class regarding books... I
actually ordered my book this weekend from an online bookstore and
the price is $70.18 for a new book...I used the ISBN code you
provided for us from online or on your syllabus...I hope that this
helps with the books..."

On page 472: tan\alpha = x_2/x_1 (not y/x).

Example 4: F(1/2)=0.6915 and not 0.5199,
which also changes the final answer to the example. Also a note
on how to read the table in the back of the book: the column
under z indicates the the argument of the distribution
function F(z) precise to the tenth. The row right to
z indicates the hundreth of the argument z. For
example: F(0.14)=0.5557 which is found in the second row
(for the 0.1 part of the number 0.14) and 5th column (for the 4
part in the number 0.14) of the table. We will do this in class
