Consider the Data Set Shown in the Table $\begin{array}{|ll|}\underline {X}& \underline{Y}\\2 & 8 \\5 & 5 \\6 & 1 \\8 & 4 \\9 & 7\end{array}$

Consider the data set shown in the table.
​
$\begin{array}{|ll|}\underline {X}& \underline{Y}\\2 & 8 \\5 & 5 \\6 & 1 \\8 & 4 \\9 & 7\end{array}$ ​
(a) Make a graph of the data points.
(b) Calculate the slope and Y-intercept.
(c) Plot the linear least squares line on your graph.
(d) Make a second graph showing the residuals.
(e) Calculate the t-value for a significance test of the slope of your linear least squares line.
(f) Using your results from (e), make a statement about the significance of the relationship between the X and Y values.
