Paper Details
School district information was examined for a random selection of states. The data below show the number of elementary schools and the number of secondary schools for each particular state. Is there a significant relationship between the variables? Predict the number of secondary schools when the number of elementary schools is 300.
Do a complete regression analysis by performing the following steps.
a. Draw the scatter plot.
b. Compute the value of the correlation coefficient.
c. Test the significance of the correlation coefficient at ? = 0.01, using Table I.
d. Determine the regression line equation.
e. Plot the regression line on the scatter plot.
f. Predict y? for a specific value of x.
