Friday!

Hope you're all ready to enjoy your weekend and get back to our first full week of school!

Hopefully you're feeling more clear after the day's discussion of independence. Remember, this will in fact be on your chapter 3 quiz Tuesday, so it might be a good idea to look at another example this weekend; that way, if you have questions, you can come after school Monday to have them clarified.

Your homework this weekend is to read chapter 4. Remember, you can take notes if you like, and if so, can use them on a potential reading quiz. It's our first chapter, so there's probably a good chance for one :).

Also, on Monday you will have a graphing calculator quiz--5/5 if you have one on your desk, 0/5 if you don't. No excuses. If you have an extenuating circumstance you should approach me before then in private (fred.carofano@gmail.com).

Enjoy the weekend! Watch some football. And keep an eye out for interesting stats we can use in class.

Here's an example for a nice answer when writing independence: Class and survival on the Titanic are not independent. Overall, approximately 32% of passengers on the Titanic survived. However, 62.46% of people in first class survived and 41.4% of second class passengers survived, showing both had a higher rate of survival. Both third class and crew had a much lower rate than the overall (the expected) rate of survival. According the data, the higher your class, the more likely you were to survive.
