Tonight please complete the following in your textbook--some practice with the types of error stuff, and some great review for Monday's test....
Weds. HW: Page 491-494: 3, 7ab, 11abcd, 13, 19bcd
- For #3, first you have to decide if the original decision was "reject" or "fail to reject the null"--if the researcher concluded that a new device IS significantly better, did he/she reject or fail to reject?
- Now, based on that, what does that tell us about our p-value? How did the p-value compare to the alpha level of 0.05 (bigger or smaller?)
- And finally, given what we know about the p-value (bigger or smaller than 0.05), do we think the same decision would be made at 1% significance level? 10%? Explain...
- For 7b use your interval to decide if you would reject or fail to reject the null, then state whether there is or is not evidence that the fraction has fallen below the 5% mark, and explain why (based on your interval)
- This is like the middle school bullying example....
- For 11d consider a consequence of each type of error--it might be easier to just describe a consequence of a Type 1 with b, and then a consequence of a Type II with c (and then you can skip d)
Extra Credit HW + Stamps (Due Friday)
- Complete AND SCORE the 2012 AP Free response on the back of Monday's HW paper....
- Score using a different color pen/pencil
- Here is the link to the scoring rubric:
- You will only earn extra credit/stamps if this assignment is completed AND scored (with notes/comments). If you do not score it and take notes on your scoring, nothing will be awarded.
- Scoring:
- Score each section (a, b, c) as E, P, or I AND provide bullets explaining why you got that score...
- If you earned a P, for example, write down notes about what you would need to add to earn an "E"
Today's Class Recap:
- Ch. 20 Vocab quiz
- HW questions (for periods D, E, H)/Discuss #3, 4
- Ch. 21 Notes:
- Defining Types of Error (Type I and Type II Errors) AND describing a consequence of each
- Completed the "top right slide" about MA seatbelts as an example of this
