Question

Q4 A contest is held on campus to decide if people like the taste of 3 novel drinks to different degrees. 18 students were selected as representative judges. Each judge Q7 tastes one drink and rates it on a scale of \( 0-10 \) where a 0 means disgusting and a 10 means heavenly tasting. Below are the 18 students' ratings of the three drinks. \begin{tabular}{|c|c|c|c|c|c|c|c|} \hline Sprite Coffee & 3 & 5 & 8 & 9 & 3 & 2 \\ \hline Ginger Coconut Juice & 6 & 4 & 4 & 5 & 2 & 6 \\ \hline Hazelnut Vodka & 4 & 8 & 9 & 7 & 9 & 5 \\ \hline \end{tabular} Q4 Which of the following equations represents the between-group variability? A. \( (3-4.3)^{2}+(5-5.6)^{2}+\ldots+(6-4.3)^{2}+(4-5.6)^{2}+\ldots+(9-4.6)^{2}+(5-4.3)^{2} \) B. \( (3-5.5)^{2}+(5-5.5)^{2}+\ldots+(6-5.5)^{2}+(4-5.5)^{2}+\ldots+(9-5.5)^{2}+(5-5.5)^{2} \) C. \( (5-5.5)^{2}+(5-5.5)^{2}+\ldots+(4.5-5.5)^{2}+(4.5-5.5)^{2}+\ldots+(7-5.5)^{2}+(7-5.5)^{2} \) D. \( (3-5)^{2}+(5-5)^{2}+\ldots+(6-4.5)^{2}+(4-4.5)^{2}+\ldots+(9-7)^{2}+(5-7)^{2} \) Q5 Which of the following equations represents the within-group variability? A. \( (3-4.3)^{2}+(5-5.6)^{2}+\ldots+(6-4.3)^{2}+(4-5.6)^{2}+\ldots+(9-4.6)^{2}+(5-4.3)^{2} \) B. \( (3-5.5)^{2}+(5-5.5)^{2}+\ldots+(6-5.5)^{2}+(4-5.5)^{2}+\ldots+(9-5.5)^{2}+(5-5.5)^{2} \) C. \( (5-5.5)^{2}+(5-5.5)^{2}+\ldots+(4.5-5.5)^{2}+(4.5-5.5)^{2}+\ldots+(7-5.5)^{2}+(7-5.5)^{2} \) D. \( (3-5)^{2}+(5-5)^{2}+\ldots+(6-4.5)^{2}+(4-4.5)^{2}+\ldots+(9-7)^{2}+(5-7)^{2} \)
