For an investigation of the mechanism of wound healing, a biologist chose a paired design, using the left and right hind-limbs of the salamander Notophthalmus viridescens. After amputating each limb, she made a small wound in the skin and then kept the limb for 4 hours in either a solution containing benzamil or a control solution. She theorized that the control solution would show better healing results than the benzamil. The accompanying data shows the amount of healing, expressed as the area (in mm2 ) covered with new skin after 4 hours. The data can be imported using the code:

 Control,Benzamil 0.55,0.14 0.15,0.08 0.00,0.00 0.13,0.13 0.26,0.10 0.07,0.08 0.20,0.11 0.16,0.00 0.03,0.05 0.42,0.21 0.49,0.11 0.08,0.03 0.32,0.14 0.18,0.37 0.35,0.25 0.03,0.05 0.24,0.16 

The biologist wishes you to run a test to see if her theory is true. Run the appropriate test and report what you have learned for the biologist?

What test should we in Rstudio for this problem?
