Page 189: 11a, 13, 35acg
- For 11a, pay attention to what information you're given, and think about what you're trying to find...
- For 13a, think about slope and what you learned in algebra--try to decide what the slope tells us about housing prices (based on) housing size...
- For 13b, substitute! (The equation is on the previous page)--remember, the sizes we "plug in" are for thousands of dollars--so think about what number you should substitute...
- For 13c, think about what we learned today!
- For 35a, use your graphing calculator! (This data should look familiar!)
- For 35c, use your graphing calculator to do "LinReg," then use the a,b values it gives you to write a linear equation!
- For 35g, first use your equation (from c) to find the predicted value...then, use the residual given to try to work backwards and find the actual value!
Good luck! More residuals tomorrow--residual plots, and what best fit means!
