Can someone help me solve this asap please!!!

Problem 3 You're working for a large chemical company in a process that uses calcium as one of its (many) inputs. The plant manager suspects that some batches of reagent furnished by the supplier differs significantly in its calcium content. The warehouse has a largc number of batches available, and you are told to test the plant manager's hypothesis. You select five of the batches at random and measure the calcium content of each batch several times, with the data shown below. Batch 1 23.46 23.48 23.56 23.39 23.40 Batch 2 23.59 23.46 23.42 23.49 23.50 Batch 3 23.51 23.64 23.46 23.52 23.49 Batch 4 23.28 23.40 23.37 23.46 23.39 Batch 5 23.29 23.46 23.37 23.32 23.38 Figure 2: Calcium content measurements. (a) Having been well trained in design of experiments, you know that you first need to use the ANOVA and, if a significant p-value is found, you then need to use the TukeyKramer HSD test to determine the pairwise differences that are significant, What are your conclusions? (b) Analyze the residuals from this experiment. Are the assumptions made in the ANOVA satisfied?
