Answer:
a. Apparent correlations between two or more variables can stimulate investigation and present possible solutions to be explored.
Step-by-step explanation:
Correlation is a scenario, where an action X causes another action Y to occur, but one of the actions does not really need to affect the other's occurrence. Correlation occurs because of the tendency of people to seek the relationship between events. The fact that two events are happening at the same time does not necessarily imply a cause and effect relationship, although there might be a possibility of such.
Correlation is used in scientific studies to draw the relationship between two events, but it does not stop at that. Through investigation has to be made to confirm that there is indeed a correlation.
The first graph is a perfect graph for this representation, from he graph we can conclude that sales were following exponential function. This can be seen by drawing a smooth trend line cutting the plotted points. Hence, this implies that the future sales can be estimated using exponential functions.
