- For #3 DO NOT do this by hand--enter the data in your calculator and use the "1 Var Stat" to find these statistics
- For #15 you should also use your calculator...
- Enter the data values for NE/MW States in one list (L1)
- Enter the data values for the S/W states in another list (L2)
- Go to your stat plots--turn one plot on and create a boxplot (with outliers) for L1, then turn on another plot and create a second boxplot for L2
- Now when you press ZoomStat you will see both (paralell) boxplots!
- Press Trace and you'll see the cursor on one boxplot to read the values and sketch the graph
- Press up/down when you're tracing to toggle between the two boxplots
- Transfer these to your paper--be sure to label which boxplot is NE/MW and which is S/W
- #24 answers (not in the back of the book):
- a.) Month 4 (April)
- b.) Month 2 (February)
- c.) Month 8 (August)

Book: Stats: Modeling the World VERSION 2 (I've found other versions, but not 2 yet...)
If you're feeling ambitious, here's (some of) Monday's homework:
Page 65: 5, 13, 26
- We're going to learn about describing distributions on Monday, so I'd hold off on writing complete answers for these, but you can start some "prep work..." (maybe just create a bulleted list for now, and then you can formally write your answers Monday)
- For #5 you can determine the shape, estimate the range, and estimate the median (for the median here just try to "eyeball" where the middle is--don't worry about counting the sample size with this histogram and finding a mroe precise median)
- For #13 you should enter the data in your calculator and use the 1 Var Stats to find the exact mean, median, IQR, standard deviation, and range; you can also describe the shape.
- For #26 you should describe the shape, estimate the median (you know n = 25), and estimate the range
- And for all of these you can look at each display to decide if there are "potential outliers
Page 96: 31bc
- For 31c we do not have the entire data set, so we must create the boxplot by hand--use your notes!
Have an AWESOME weekend! We can finally go outside without sweating nonstop!
GO GMEN!!!
(Oh....one more thing....you might want to do a little review so you're ready for the pop quiz I'm going to surprise you with Monday morning--it's 4 multiple choice questions. Be sure you can find the median for a given histogram, determine the IQR given a picture of a boxplot, and determine if a histogram is symmetric/skewed left/skewed right...)
