Answer
To complete the time series graph:
-
Plotting Points:
- Plot the average number of customers per day for each quarter in the years 2015 and 2016 on the graph.
- For 2015, plot the points:
- Jan-Mar: 119
- Apr-Jun: 264

- For 2016, plot the points:
- Jan-Mar: 130
- Apr-Jun: 304
- Jul-Sep: 381
- Oct-Dec: 192
-
Connecting Points:
- Connect the plotted points for 2015 with a line, then do the same for the points in 2016.
-
Labeling the Axes:
- Ensure the vertical axis is labeled as 'Average number of customers per day' and the horizontal axis is labeled as 'Year and Months'.
Your graph should clearly show trends over the two years.
