Concept explainers
a.
To plot: A regression curve on a scatter plot using the data given below
Given information:
The data is given
The plot of the
Where
The regression model based on the data and the scatter plot is a cubic regression model.
Graph is given below.
b.
To Explain: how far the person from motion detector to when the person changes the direction using the regression model .
Where distance is in
.
Given information:
The regression curve is given below.
Where distance is in
Based on the data and regression curve can understand the model is cubic regression model where the relation between time versus distance is about f
Based on the time can find the distance the from the motion detector by substituting the value for time
