The proprietor of a fabrication shop wants to know if there is a relationship between the number of hours on the lathe machine and the income (Php in hundred thousands) for each month a year. Based on computation, r = 0.61 and the scatter plot, what does the result imply? Explain your answer.
When creating the dot plot, how are multiple data points for a single score displayed?
a. A larger size dot is used; the size of the dot is directly proportional to the number of data points.
b. More than one dot is used; dots are placed side by side creating a wider interval.
c. A dot plot is innappropriate when multiple data points exist for a single score.
d. Multiple dots, representing each data point, are replaced on top of one another.
