Question

2. The data in the accompanying table represent the concentration of glucose in the blood serum of an adult patient. On four consecutive days, a blood sample was drawn from the patient and analyzed in triplicate. The variance for a given sample is an estimate of the measurement variance while the day-to-day variance reflects both the measurement variance and the sampling variance. (20 points) \begin{tabular}{cccc} Day & \multicolumn{4}{c}{ Glucose Concentration, \( \mathbf{m g} / \mathbf{1 0 0} \mathbf{~ m L} \)} \\ \hline 1 & 62 & 60 & 63 \\ 2 & 58 & 57 & 57 \\ 3 & 51 & 47 & 48 \\ 4 & 54 & 59 & 57 \\ \hline \end{tabular} a. Perform an analysis of variance and see whether the mean concentrations vary significantly from day to day.
