Thursday HW

Tonight, please complete the two hypothesis tests provided (on the worksheet) in class (or below).

This is a great overview of how to conduct a full test--just like last night's homework! Put in max effort!

Here are the correct pvalues/zscores for your hw so you can check:
  • For the problem about "obtaining news from the internet" you are going to get a super low p-value! 
    • p-hat is .33 for this problem! (B/c p-hat is from "the report") This is trickily worded.
    • The p-value = 1.459E-13 = .0000000000001459!
    • z-score = 7.391!
  • For the problem about women over 40 scheduling mammograms...
    • p-value = .00002217 (or 2.2175 E -5)
    • z-score = 4.084


Tomorrow we do some chapter 20 practice! We'll have our ch. 20 vocab quiz on Monday, along with 3 multiple choice questions about intervals! (Period A: this was the "pop test" I mentioned in class--so it's Monday with your vocab!)
