Weekend HW:

I hope you're feeling confident about today's test! I hope to get them graded by Monday--no promises (dad life can get pretty hectic), but I will do my best to make that happen.

On Monday we'll start our first full week of "real AP Stats." No more textbooks or Star or syllabus stuff, just our class routine of warmup, learn stuff, practice, assessment...and I can't wait! So be ready for some new stuff next week (lots of writing about the graphs we now know how to create).

This weekend, please complete the following for homework:

Page 65: 7ab, 9a and....

Page 91: 13, 23abc, 29ab, 47

  • For number 7a (p. 65)you are asked to describe the distribution--for now, I just want you to write a couple sentences describing what this graph tells you about sugar content (%) of different brands of breakfast cereals. You won't need any fancy statistical language here, this is just an intro to us writing about graphical displays
  • For number 13 (page 91) you must show work to determine if there are outliers--you can't just create a boxplot on your calculator (you can use the boxplot on your calculator to check your answer, but show the math that proves these are outliers...)
  • And remember check your answers in the back of the book!
    • Your answer for #7a should include the following info--I wouldn't expect you to use the vocab in the back of the book (yet), so use this as your key
      • The distribution of sugar content has two clusters of data
      • One cluster is from 0-24(ish) % sugar (lower sugar amounts), and the other is from 40 to 56%(ish) sugar (higher sugar amounts)
      • Generally, cereals tend to either have less than 24% sugar or more than 40% sugar,with few brands "in the middle"
And finally, here's Monday night's homework if you're feeling ambitious and want to get a head start:

Page 65: 9b (again, write a couple sentences describing what you see, no fancy vocab yet), 11ac, 17, 19a

Page 91: 3 (but use your calculator, don't do this by hand)
