Question: Modern software applications require rapid data access capabilities. An experiment was conducted to test the effect of data file size on the ability to access the files (as measured by read time, in milliseconds). Three different levels of data file size were considered: small – 50,000 characters; medium – 75,000 characters; or larger – 100,000 characters. A sample of eight files of each size was evaluated. The access times are recorded on the tab Access1. (10 points)

a) Is there evidence of a significant difference among access times for the three file sizes at the .05 significance level?

b) Interpret your results.
