QUESTION 1
The data in the table below represents the score in percentage of 12 Mathematics learners in their
Grade 12 trial examination and their corresponding final examination.
1.1 Represent the information above in a scatter plot
1.2 Determine the equation of the least squares regression line for this set of data
1.3 Hence, predict the final percentage for a learner obtaining 73% in the trial examination.
Give your answer to the nearest percentage
1.4 Calculate the correlation coefficient for the above data
1.5 Do you think by using the least squares regression line one can accurately predict a
learner’s final percentage? Provide Mathematical justification for your answer.
QUESTION 2
The table below shows the total fat (in grams, rounded off to the nearest whole number) and
energy (in kilojoules, rounded off to the nearest 100) of 10 items that are sold at a fast-food
restaurant.
2.1 Represent the information above in a scatter plot
2.2 The equation of the least squares regression line is yˆ 154,60 77,13x
2.2.1 An item at the restaurant contains 18 grams of fat. Calculate the number of
kilojoules of energy that this item will provide. Give your answer rounded off to
the nearest 100kJ
