We plan to test on Chapter 15 on Tuesday, April 14. Until then we will be doing problems from old exams that relate to linear regression and inferences about the slope (the problems you Hawaii folks picked up on Tuesday!!!). We covered this stuff first semester when we did regression.

Our tentative plans for tests for the rest of the semester. . .

Write up the responses to the three free response questions discussed in class in your spiral notebooks.

Notes for the 2008 problem, part c: Follow their directions. Average the two proportions. For the standard deviation you will have to find the square root of the variance of the average. Yiles! Sounds difficult.

Variance of the average = 1/4 variance of x + 1/4 variance of y.
