# Project #90425 - PHD Level: Data analysis assignment

Very Time sensitive assignement, if you are one hour latter than neede i willl cancel, use excel and show ful calculation.

Is there a linear relationship between the speed at which a car is driven and the gas mileage? A car was driven on a test track for one hour at each of 5 speeds and the gas mileage calculated. Here are the results:

 Km/Hour Km/Liter 30 24 50 28 70 30 90 28 110 24

Draw a scatterplot and determine whether there appears to be a linear relationship between speed and gas mileage. If so, describe the relationship, calculate r, and determine what percentage of the variability in the gas mileage can be explained by the variability in the speed.

Can you suggest any alternate options? Why?
