Open “Prep 2.2” Excel file. Data for the two questions can be found on different sheets. Use the Excel file for computation and charts and a Word document for your written answers. Save and upload both files to Canvas.
- Open “transportation” sheet in “Prep 2.2” Excel file. (1 point)
The city’s Department of Transportation has been keeping track of accidents on a particularly dangerous stretch of highway. Early in this year, the city lowered the speed limit on this highway and increased police patrols. Data on number of accidents before and after the changes are presented in the Excel sheet. Did the change work? Is the highway safer? Construct a line chart in Excel to display these two sets of data and write a paragraph (150 words) describing the changes. Copy-paste the chart from MS Excel to MS Word and add it to your text.
