Next week is the end of the 2nd “six” weeks, and our last test of the grading period is on Tuesday/Wednesday (Nov. 2/3).  Here is the review sheet:

Also, here is a reference sheet with the trig identities and formulas, in case you find it helpful:


AP Stat – HW #9 (due Thursday, Oct. 28)

  AP Statistics

(FYI, there was a mistake in the numbering of the assignments last time, so this is actually homework #9)

Here is the homework:

  • Finish the Chapter 7 Quiz (it was a take-home – if you missed class, see me to get a copy!)
  • Do the horsepower lab for HP vs. time (we did HP vs. mass during class notes). 

    Here is the data. (look on page 2 or 3)

    Make sure you use the info for your class period, put the time data in L1, HP data in L2, and do the same 5 questions that we did in class using your calculator to aid you.

  • Computer Printouts Worksheet: 8 Computer Output worksheet.pdf 
    (I know #4 is a little tough but do your best!)
  • A few book problems (sorry!): Ch. 8, (p.189), #1ac, 3, 14, 16.

AP Stat – HW #8 (due Tuesday, 10/26)

  AP Statistics

Here’s the assignment for the weekend:

  • Ch. 7, #18*, 24, 25, 28. 30
    *for #18, use your calculator for the scatterplot and draw a *sketch* on your paper.  Your graph should include labels for the axes, as well as a *title* for the graph.
  • Read p.174-175, and answer “just checking” #3-6 on that page.
  • Read p.178, “Residuals Revisited”.  Understand that it is a *good* thing for the residual plot to look like “nothing”.
  • Ch. 8, #27abc.  For a challenge, do part (d) after you do all of the reading.  Show all work!!!

As a reminder, there is a solo (non-group) quiz over Chapter 7 on Tuesday.

The current plan is to have our group quiz over chapters 7-9 on Monday, November 1, and the chapter 7-9 major test on Wednesday, November 3.  Stay tuned on that~
