Final answer:
The desired outline width is 2 1/4 pt. This outline adjustment is a common feature in spreadsheet software for graphing purposes, and understanding outliers is key in data analysis.
Step-by-step explanation:
The desired outline width specified in the question is 2 1/4 pt. The outline width is a formatting option in computer graphics and spreadsheet software, such as Microsoft Excel, where visual elements of charts can be customized for clarity and visual impact. When given a task to change the outline width, you adjust the visual property of the selected element, in this case, the outline of the 2019 data point in a Gross Profit data series to make it stand out more.
In dealing with graphs on calculators, like plotting a scatter plot and understanding the concept of outliers, the focus shifts towards statistical analysis. An outlier may significantly skew the representation of data, affecting the slope and position of a best-fit line. The ability to manipulate and understand the consequences of changing data presentation is an essential skill in data analysis and is often taught in high school computers and technology or mathematics classes. Identifying outliers helps in making more accurate predictions and analyses of a data set.
