Answer:
3 1/2 hours.
Step-by-step explanation:
We subtract>
Number of hours worked on a Saturday
= 7 3/4 - 4 1/4
= (7 - 4) + (3/4 - 1/4)
= 3 + 1/2
= 3 1/2 hours.
r value i.e Correlation between x value and y value = 0.769
=Standard deviation of the x-coordinate = 5.508
=Standard deviation of the y-coordinate = ?=k
Slope of line is given by formula
If slope of line is m, then
m =
m=
Substitute the value of k, i.e Standard deviation of the y-coordinate and then you can get the slope of line to three decimal places.
