1.5 Cont.
Warm-up (IN)
Learning Objective: to create a scatter plot and use the calculator to find the line of best fit and make predictions.
(same as last time!)
Acuity and HW/INB check
Notes
EX 1 – The table gives the average speed of an airplane during the first 10 minutes of a flight, with x in minutes and y in miles per hour.
x 1 2 3 4 5 6 7 8 9 10
y 180 250 290 310 400 420 410 490 520 510
a. Draw a scatter plot and find the equation of the line of best fit.
b. Use your equation to predict the speed of a plane after 22 minutes.
c. Use your calculator to find the regression line, then check your prediction.
Correlation Coefficient – Indicates how closely the data points cluster around the least squares line
r
HW – p. 40 #1-9, 15-20, 22, 27-35
Out – How can least squares lines be useful?
Summary – I can remember…
Challenge Problems!
Activities online are EC, too!
POW!!!!
