Question

A. What is the equation for the Linear Regression Line? Response area B. There is a Response area correlation between the test marks and the homework marks. C. The slope of the line of best fit can be used to make a probabilistic interpretation that states Response area


X Axis:

Rob: 61
Thomas: 95
Mark: 44
Wanda: 93
Judy: 63
Haydn: 80
Barbara: 62
Karen: 95
Marilyn: 65
Phil: 88

Y-Axis:

Rob: 35
Thomas: 50
Mark: 5
Wanda: 50
Judy: 15
Haydn: 34
Barbara: 16
Karen: 50
Marilyn: 7
Phil: 38

X-axis = test mark
Y-axis = Homework mark


y = 0.7x - 38

The homework mark increases 0.89 points for every 1 pt. on the test mark.
The test mark decreases 0.7 pts for every 1 pt on the homework mark
y = 0.89x - 36.7
no correlation
positive
The test mark increases 1pt for every 1 pt on the homework mark
The homework mark increases 37 pts for every 1pt. on the test mark
negative
y = -37x + 1
y = -x + 37

Answer 1

Based on the context provided, here are the appropriate responses:

A. The equation for the Linear Regression Line?
**y = 0.7x - 38**

B. There is a Response area correlation between the test marks and the homework marks.
**positive**

C. The slope of the line of best fit can be used to make a probabilistic interpretation that states
**the homework mark increases 0.7 points for every 1 point increase in the test mark.**
