This week's assignments.

Digestive system:  please read sections 43.2 and 43.3 in the book. Have this done by monday.

Data Manipulation quiz/homework:  The thing I want you to test is whether my 1st period class is more likely to do homework earlier than my afternoon classes.  You will need to write a null hypothesis, figure out how to approach this data (something of a puzzle), run a t-test to check significance, calculate mean time of homework and standard deviations.  Here are the links for t-tests:  website, chart
Have this write-up for me by Monday.  remember, it is OK to work in groups, but then it should be graded as homework, rather than a test.  Good luck.
