27.7% of the variation in fastest serves is accounted for by the LSRL equation where x = height.
A: Residuals are the predicted values minus the observed responses
B: In a study where a student is scared with a variety of monsters and then their blood pressure is measured. The explanatory variable is...?

On page 98 of your notebook do #5 & #6
#5: A
#6: E
On p.101 Do #11 parts D & E
slope = 84.98
The serve speed is predicted to increase by 84.98 km/hour for each additional (1m) of height
This prediction would be extrapolation because 1.7 is outside of the domain of heights that were inspected. This prediction would not be reliable.
Dr. Smartypants says his correlation coefficient was 1.86 on a recent study of number of fans at games and amount of hot dogs in the freezers at the stadium. Something doesn't seem right...what is it?
r cannot be more positive than 1, so either he is trolling you or he needs to relearn correlation because his is wrong.

Do #7 & #8 on page 98 of your notebook
#7: D
#8: E
On p.101 Do parts F & G
F: 0.526 ; The linear relationship between height and serve speed is positive and weak
G: residual = -13.8688 ; The LSRL overpredicted the serve speed for a player that is 2.06 meters tall
Given ln (y) = 3.6 - 2.5 (x)
If x = 2 , then y = ?
y = 0.25
e to the power of -1.4

Do #9 & #10 on page 99 of your notebook
#9: D
#10: B
On p.102 Do #12 parts A & B
A: A linear model is not appropriate because the residual plot shows a clear curved pattern
B: Model III is the best model because it has the highest value for r squared and it has a random scatter of points above and below the zero line on the residual plot
Which statement is false?
A. The LSRL and r are resistant to outliers
B. The residual plot is curved, so the scatterplot is not linear
C. Correlation implies causation
C is false
