Finally, sales per square meter and sales floor space of the store i the only compounding with a negative relationship. The two variables have a correlation coefficient of -0.29379 which implies that when 1 variable increases, the other one decreases.The graph above displays data points that resemble a rising line from the left hand gradient to the right-hand(a) hand side of the graph. Even though most of the points are clustered to the left of the graph, the side of meat of the assumed line (line of topper fit) is positive. This shows that there is a positive correlation which implies that the much the depend of full-timers, the more the sales per square meter. This plot supports the deliberate correlation coefficient (0.237185).Since the calculated t is greater than the tabulated t (4.8769321.96), we stop to accept the null hypothesis and conclude that the relationship exists between sale s per square meter and the number of full-timers.From the above graph, data points resemble a rising line from the left hand side to the right hand. Most of the points are clustered to the left of the graph but the slope of the assumed line (line of best fit) is positive. This depicts that there is a positive correlation implying that the more the number of part-timers, the more the sales per square meter. Moreover, it supports the calculated correlation coefficient of the two variables (0.050085).Since the calculated t is smaller than the tabulated t (1.001704
