Answer to Problem 28AYU
Explanation of Solution
Given:
Calculation:
Draw a scatter diagram of the data treating speed as the independent variable and find the type of relation appears to exist between speed and miles per gallon
From the scatter plot of the data it is seen that there is quadratic relation exists between speed
and miles per gallon.
Conclusion:
Thus, the scatter diagram is drawn.
