Thursday HW!

**If you were absent yesterday or today you must make up any missing tests before Thanksgiving break...**

  • During any free period/lunch/study hall Friday, Monday, Tuesday
  • Or, after school Tuesday
  • Worst case: make up the test during Stat class, but then you will miss any notes and have to catch up on those

Let's do a little intro to probability for homework! Tomorrow it's new seats, new unit, a fresh start, and lots of math! I'm pumped--see you there!

Tonight, please complete the following in your textbook (or, today, I put the questions and answer below so you don't need your book):

Page 340: 9, 11, 17, 23a

  • For 9, a probability distribution is possible if....
    • All probabilities sum to 1
    • All probabilities are between 0 and 1 (inclusive, meaning they can equal 0 or 1)
      • No negative probabilities
      • No probabilities greater than 1
  • For 11, don't overthink these...
    • b.) "No more than 1 repair..." Think: How many repairs would satisfy "no more than 1?"
    • c.) "Some repairs..." Think: what numbers of repairs would satisfy "some repairs?"
  • In #17 the data is super old (2001--I was still in high school then!), but it might be interesting to think about how opinions may differ today (17 years later) than they did in 2001.
    • For the math here, you got this. Don't overthink it.
  • For 23, this is like our spinner stamp--basic probability!
