a) The company have checked the capacitances of a batch 120 of 100 µF capacitors and given you the results as shown in the group frequency table 1 below. Use that data given to calculate the mean and standard deviation of the data. You should provide clear explanation of the calculations used and a suitably chosen graphical representation of your results suitable for a non-technical audience. You may use a spreadsheet for these calculations, but you must provide clear evidence of the formulas used in each cell and submit the spreadsheet file with your report.
