Please help with number 12.11 parts b and d only. The Mitcherlich equation referenced below is:

12.10 Consider the model y = 01 -Oze-3x + E This is called the Mitcherlich equation, and it is often used in chemical engineering. For example, y may be yield and x may be reaction time.12.11 The data below represent the fraction of active chlorine in a chemical product as a function of time after manufacturing. Available Chlorine, y, Time, X; 0.49, 0.49 8 0.48, 0.47, 0.48, 0.47 10 0.46, 0.46, 0.45, 0.43 12 0.45, 0.43, 0.43 14 0.44, 0.43, 0.43 16 0.46, 0.45 18 0.42, 0.42, 0.43 20 0.41, 0.41, 0.40 22 0.42, 0.40, 0.40 24 0.41, 0.40, 0.41 26 0.41, 0.40 28 0.40, 0.40, 0.38 30 0.41, 0.40 32 0.40 34 0.41, 0.38 36 0.40, 0.40 38 0.39 40 0.39 42 a. Construct a scatterplot of the data. b. Fit the Mitcherlich law (see Problem 12.10) to these data. Discuss how you obtained the starting values. c. Test for significance of regression. d. Find approximate 95% confidence intervals on the parameters , 02, and 63. Is there evidence to support the claim that all three parameters are different from zero
