Problem 3d Some researchers have conjectured that stem-pitting disease in peach tree seedlings might be related to the presence or absence of nematodes in the soil. They conducted an experiment to compare peach tree seedling growth with soils and weeds using one of three treatments: A: Control (no herbicide) B: Herbicide with Nemagone C: Herbicide without Nemagone The researchers randomly assigned 6 of 18 seedlings chosen for the study to each treatment group. They treated the soil and weeds in the growing areas for the three groups with the appropriate herbicide. At the end of the study period they recorded the height (in cm) for each seedling. The results are recorded in the Excel file Final_P3_Data.xlsx. You are asked to determine if there is a difference in the mean height for the different groups. d) Based on the ANOVA model Yij H+T+ E provide a point estimate for g, , the standard deviation of the error s in the model. Use 2 decimals for your answer.
