Please help with this problem, on calculating shear stress

The data was collected using a Haake viscometer during an experiment to optimize the process of canola-oil based resin production. The data was collected at 30 C. Shear rate (s) Viscosity (mPa.s) 13.5 595 22.5 475 37.5 415 62.2 320 104.5 260 162.1 234.5 167.2 235 a) Calculate the shear stress and plot a professional scatter plot of shear rate and shear stress b) Determine the values and units of K and n for this sample. c) Is the resin Newtonian or shear-thinning?
