Final answer:
Option b. Data points failing in a linear pattern suggest a weak relationship between cost and volume is the false statement.
Step-by-step explanation:
The false statement among the given options is option b. Data points failing in a linear pattern suggest a weak relationship between cost and volume.
In a scatter plot, if the points do not exhibit a clear linear trend and are scattered randomly, it indicates a weak relationship between the variables. It means that there is no strong correlation or association between cost and volume.
Other statements - a, c, and d are true. Scatter plots help identify outliers, managers use judgement to classify cost behavior in account analysis, and volume should be plotted on the x-axis and cost on the y-axis while creating a scatter plot.
