3. Calculate the \( 98 \% \) confidence interval for the difference in signal strengths for the two energy inputs (100 Watt and \( 150 \mathrm{Watt} \) ) A laboratory is testing different preparation methods for serum. The concentration of Albumin in human plasma serum \( (\mathrm{n}=12) \) is considered an important factor. The data for the quantification of Albumin, in gram/deciliter, is given below. Determine if the preparation methods result in a significant change to the concentration of albumin in serum \( (\alpha=0.05) \) (Hint: Apply one-way anova, you can check out Example 3-1 on Page 74 in your textbook ) Data for the quantification of albumin for different methods.
