1. Does the relationship between number of people and the bill appear to be weak, moderate or strong?


2. Does the relationship between number of people and the bill appear to be linear?


3. The equation of the line of best fit is Bill = 5.80 + 11.15 · People. (y=5.80+11.15x) Sketch this line on the scatterplot.


4. Interpret the slope of the line of best fit in the context of this problem.


5. Note that the points in the scatterplot do not all lie on the line. What could explain this variability?


6. Use the equation of the line of best fit to estimate how much would you predict the bill to be for a party of 8?


7. There was one party of 8 whose bill was $82.50. Did they pay more than or less than the predicted amount? How much more or how much less did they pay?

Answer 1

In the above scenario, for question 1 and 2, we can say that relationship does depict or appear to be fairly strong and also linear as the points on the graph doesn't move far from a line.

What is the relationship about?

Other answers are:

• The answer to question 3 scatterplot graph is given in the image attached.

The  Interpretation of the slope of the line of best fit in the context of this problem is that the additional person added to the party will  bring or add about $11.15 to the bill above.

 The variability can be shown or explained by the differences that is seen in what the parties in the graph has ordered to eat or drink.

Since the party of 8 paid were said to have paid (95 - 82.50 =12.50) therefore, 12.50  is known to be less than the predicted amount.
