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.
