a) Based on the given table, the most appropriate scatter plot from the given choices is Scatter plot A because The data for weekly sales between 10000 and 18000 dollars are scattered between the floor space 4000 and 6000 square feet.
b) The relationship between X and Y is C. Positive and E. Nonlinear.
A nonlinear relationship exists when the trend line of X is plotted against the Y-values and the line is not straight but curved. The implication is that the value of Y does not depend on the value of X.
Thus, since the relationship between floor space in square feet (X) and the Weekly Sales in dollars is unpredictable, there is a nonlinear relationship.
