The results shown below represent Ca results in ppm determined by an ion-selective electrode (ISE) method, by EDTA titration, and by atomic absorption spectrometry: (15 points) \begin{tabular}{|c|c|c|c|} \hline Repetition No. & ISE & \begin{tabular}{l} EDTA \\ Titration \end{tabular} & Atomic Absorption \\ \hline - 1 & 39.2 & 29.9 & 44.0 \\ \hline 2 & 32.8 & 28.7 & 49.2 \\ \hline 3 & 41.8 & 21.7 & 35.1 \\ \hline 4 & 35.3 & 34.0 & 39.7 \\ \hline 5 & 33.5 & 39.2 & 45.9 \\ \hline \end{tabular} a. State the null and alternative hypotheses. b. Determine whether there are differences in the three methods at the \( 95 \% \) and \( 99 \% \) confidence levels. c.
