Write a Matlab script m-file that loads in this file and fits a polynomial of an appropriate order to the data. The script should then produce a plot of distance against effective dose and display the fitted curve on the same figure. The fitted curve should be used to compute the expected effective radiation dose at a distance of 3.25 m. All required information is attached below.

Positron emission tomography (PET) imaging involves the patient being injected with a radioactive substance (a radiotracer), the concentration of which is then imaged using a scanner. Staff involved in performing PET scans receive some radiation dose as a result of being in the vicinity of the patient while the radiotracer is inside their body. A study is investigating the effective radioactive dose to which staff are exposed as a result of performing PET scanning (e.g., see [2]). Data indicating the effective radiation dose (in microsieverts, Sv ) as a function of distance (in meters) from the patient are available in the file dose_data.mat. Write a MATLAB script m-file that loads in this file and fits a polynomial of an appropriate order to the data. The script should then produce a plot of distance against effective dose and display the fitted curve on the same figure. Finally, the fitted curve should be used to compute the expected effective radiation dose at a distance of 3.25m. Workspace Editor - untitled2 distance x dose x 16 double
