Thursday HW, Weekend HW, Monday HW....

Great job today thinking critically/conceptually about some deep stuff! Tomorrow we'll look at how to create a residual plot on our calculator, then we'll look at what R^2 means with an AP Stat Guy video.

Here's your homework for the next few days in case you want to get a head start....

Thursday's HW:

• Page 189-191: 3, 15a, 19be
• For 15a use the given scatter plot and residual plot to determine if a linear model is appropriate--there are three things you should check!
• For 19be you need the equation of the line...
• Look back at #15 for the equation...
• The slope is the coefficient to the x variable, or the 0.065052
• The y intercept is the constant or the 0.154030
• DO NOT ROUND THESE NUMBERS. Use the full decimals given to write your equation, then use that equation for 19be

Weekend HW:

• Our weekend HW recaps a bunch of the stuff we've learned--try this without your notes! If you can answer all these without notes then you know (almost) everything you should at this point in the chapter!
• The title of the weekend HWis "Chapter 8 Quiz: The LSRL"--this one isn't a quiz, but it's a sample of what a chapter 8 quiz would look like!
• Ch. 8 Summary HW! (Click Me!)
• I'll post a key tomorrow...

Monday's HW:

• Feeling super crazy and want to realllly get ahead? Here's Monday's hw....we don't know how to do all of it yet, but we can do some.
• Page 194-195: 41, 47
• All parts! It looks short but 41 has a-g and 47 has a-f
• For both of these you need to write the equation of the LSRL from a "computer output..."
• The slope is always the coefficient to the x variable 
• The y intercept is always the "constant"
• So, for example for 41 the slope is the 0.004 and the y-intercept is the 15.3066
• Or for 47 the slope is the -3.23 and the y-intercept is the 1676 (all the other stuff in 47 is irrelevant)
