I don't see them either. There is a chart where the answers should be though. I was reading the paragraph explaining the chart, but I don't understand how it works. =[
the answers are on page S4, on the right hand side of the page. also, for question 12, i kept getting the answer for m.a.d. wrong. can someone help me. i tried using the formula we did in class, but i kept getting 68 for some reason.
Can someone explain to me how to use the lists to calculate the M.A.D? I dont think i'm doing it right cuz my calculator keeps giving me different numbers. I also didn't understand 7b?? same with #13 i dont know what data they are talking about
To calculate MAD using lists: 1.Values: Enter values in L1.
2.Mean: Press 2nd Mode. Then go to Catalog (2nd-0) and press the division symbol (M) to bring up all things starting with M. Find mean and enter in L1. (should look like- mean(L1))Get answer and enter it into L2.
3. Deviation: Highlight L3 and enter L1-L2.
4. Absolute Deviation: Highlight L4. Enter abs(L3). (Get abs() in MATH.)
5. Mean of Absolute Deviation: Press 2nd Mode. enter mean(L4). Get answer (ROUND TO TENTH).

Hey i did my self test and then went back to the book to correct it but there were no answers to the self test.
Did anyone else get this problem?

Yeah i agree. I also don't understand 13. I just guessed and got it right.
oh. I haven't checked yet i almost forgot but i don't even know how to guess on that problem.
in 13, they are talking about the movie price data.

6. Write answer in math journal =].
TADA!
Hope this helped.
