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!)
