?4 RE Time and Motion? In a physics experiment at Doane College, a soccer ball was thrown upward from the bed of a moving truck. The table below lists the time (sec) that has lapsed from the throw and the height (m) of the soccer ball. What do you conclude about the relationship between time and height? What horrible mistake would be easy to make if the analysis is conducted without a scatterplot? T i m e ( s e c ) H e i g h t ( m )

Solution 4 RE Step 1 : Given, In a physics department at Doane college, a soccer ball was thrown from the bed of a moving truck. Below table lists the time that has lapsed from the throw and the height of the soccer ball. We have to analyze that there is any linear relationship between time elapsed and height of the soccer ball. Following are the steps to analyze correlation and regression from Stat Disk . Enter the dataset in stat disk AnalysisCorrelation and regression. . Choose level of significance evaluate . After obtaining the results click ok on Scatter plot. The Scatter plot for the given data is We can see that the points are are not showing any pattern, points are scattered around the line. So, we can say that the plot is not linear and it is non linear. Step 2 : The correlation and regression for the given data is
