Answer #1
Dot plot:
Regression equation:y = -0.70x + 43.92
Using your equation, estimate the mass of the object at 11 minutes.
x = 11
y = -0.70*11 + 43.92 = 36.22 grams

A student recorded the speed of an object as a function of
time and obtained the following data:
Reading no. Time (s) Speed (m/s)
1 2.0 1.20
2 3.0 1.70
3 5.0 2.70
4 5.50 2.95
5 6.60 3.50
6 8.0 4.20
1) Prepare a sheet of graph paper for plotting Speed versus
time. You should make the speed on the vertical axis and the time
on the horizontal axis.
2) Plot the measured values on the speed-time graph.
