Background: To prevent crashes caused by running red lights, many states are installing cameras at dangerous intersections. These cameras are used to take photographs of the license plates of vehicles that run a red light. The Virginia Department of Transportation (VDOT) obtained data on the number of crashes per year caused by running a red light at 13 intersections in Fairfax County, Virginia. Source: Virginia Transportation Research Council, "Research Report: The Impact of Red Light Cameras (Photo-Red Enforcement) on Crashes in Virginia", June 2007 Directions: Perform an appropriate significance test to determine whether or not the reduction in the number of crashes was statistically significant. 1.

MAT 312 PLEASE HELP After being hired as a financial advisor for a large real estate company, you have been tasked with exploring trends between home size (square ft) and property taxes to see if a relationship exists and if that trend can be applied outside of just the sample data. In the Excel Lab #5 Data File, you will find raw data on sheet 1. However, to simplify your calculations, you have only been asked to test a random sample of 10 homes. So, your first step will be to randomly select data from 10 of the homes and paste them into sheet 2 called “sample data”. This will be the data that you will analyze. (You can generate 10 random numbers between 5 and 30 however you want for your sample, but know that there is essentially no chance two students should have the same 10 samples). Within the Excel spreadsheet, use the Excel tools/functions to calculate the correlation coefficient, test statistic, and p-value. You will also use Excel to generate a scatterplot of your sample data…
