Hi! I would be grateful if you answer this question with step by step explanation. Thanks in advance!!


\f1. Given the experimental Planning Matrix in the Excel file (download from course website), do the following: (a) Determine the corresponding design matrix. What essential aspect is the above planning matrix different from a design matrix? Why so'? (b) What kind of design is employed here? Construct a geometric view of this design. Identify factorial points (i.e., corner points) center points and star points. (c) Identify nF, nc. Estimate the variance of the error term (a). (d) Discard all data at star points, construct an ANOVA table utilizing only factorial points and center points. Conclude if the curvature is significant based on the ANOVA table.
