Could you please do this with the formulas in legible handwriting so I could better understand how to do this?

33. A start-up firm has kept careful records of the time required to manufacture its product; a shutoff valve used in gasoline pipelines. Cumulative Number Number of Hours Required of Units Produced for Next Unit 50 3.3 100 400 600 1,000 10,000 2.2 1.0 0.8 0.5 0.2 a. Compute the logarithms of the numbers in each column. (Use natural logs.) b. Graph the In(hours) against the In(cumulative units) and eyeball a straight-line fit of the data. Using your approximate fit, estimate a and b. c. Using the results of part (b), estimate the time required to produce the first unit and the appropriate percentage learning curve that fits these data. d. Repeat parts (b) and (c), but use an exact least squares fit of the logarithms
