Question
QUESTION 2 1.The Preserve has a Linear Prediction model it uses for a Human Disturbance Index (0 - 100): Disturbance Index = 10.4 + 1.4
QUESTION 2
1.The Preserve has a Linear Prediction model it uses for a Human Disturbance Index (0 - 100):
Disturbance Index = 10.4 + 1.4 * Developed Lots per Square Mile
(with count of Developed Lots going from 2 to 64)
a) What are the values for a and b in this model?What do they represent?
b) For an area with 15 Developed Lots, what is the prediction for its Disturbance Index?
10 points
QUESTION 3
1.For the Disturbance Index Prediction model, a Sample of 60 areas has a Developed Lot Standard Deviation sX= 4.5 and a Disturbance Index Standard Deviation of sY= 15.0.
a) What Correlation would we calculate for the two Variables?What does the Correlation represent?
b) What Coefficient of Determination would we calculate for the two Variables?What does r2represent?
10 points
QUESTION 4
1.For the Conservation Index model, we have a new Sample of 12 measurements:
Developed Lot Counts = {59, 13, 23, 52, 62, 24, 10, 38, 57, 7, 8, 31}
Disturbance Index = {82, 28, 65, 93, 69, 5, 23, 65, 77, 38, 23, 89}
a) Build and show the "best-fit" Linear Prediction model for this Sample. (3 decimal places)
What Correlation r does it have?What Determination r2does it have?
