Analysts claim that the population mean of the variable Energy is greater for households that can afford to pay for a one-week annual holiday per year away from home than the ones that do not have this capacity. 2.1 State the null and the alternative hypothesis of the above research question. 2.2 Compare the variances in the two sub-populations, using an appropriate test, at \alpha = 5%. 2.3 Based on the findings of 2.2, test 2.1 at \alpha = 5%. 2.4 What is your conclusion from 2.3? \begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|} \hline A & B & C & D & E & F & G & H & 1 & J & K \\ \hline Number & Area & Rooms & Holiday & Car & Income & Members & Energy & Arrears & Members_Bin & Rooms_Cat \\ \hline 92 & 411,87 & 1 & 0 & 0 & 6693,18 & 5 & 584,98 & 1 & 1 & 1 \\ \hline 93 & 139,76 & 3 & 1 & 1 & 33915,15 & 2 & 584,98 & 0 & 0 & 2 \\ \hline 94 & 111,83 & 3 & 1 & 1 & 12801,59 & 2 & 854,24 & 0 & 0 & 2 \\ \hline 95 & 128,83 & 5 & 1 & 1 & 45209,04 & 3 & 866,85 & 0 & 1 & 3 \\ \hline 96 & 181,85 & 3 & 1 & 1 & 49404,84 & 4 & 752,12 & 0 & 1 & 2 \\ \hline 97 & 211,45 & 4 & 1 & 1 & 28856,6 & 4 & 1253,53 & 0 & 1 & 2 \\ \hline 98 & 80,50 & 3 & 0 & 0 & 9078,48 & 1 & 584,98 & 0 & 0 & 2 \\ \hline 99 & 383,52 & 3 & 1 & 1 & 39311,09 & 3 & 722,37 & 0 & 1 & 2 \\ \hline 100 & 77,43 & 2 & 1 & 1 & 8741,42 & 1 & 668,55 & 0 & 0 & 1 \\ \hline 101 & 62,31 & 4 & 1 & 0 & 5487,17 & 1 & 1253,53 & 0 & 0 & 2 \\ \hline 102 & 234,38 & 2 & 1 & 0 & 2080,32 & 1 & 584,98 & 0 & 0 & 1 \\ \hline 103 & 236,57 & 3 & 1 & 1 & 47707,95 & 5 & 2089,22 & 0 & 1 & 2 \\ \hline 104 & 135,82 & 3 & 1 & 1 & 25546 & 2 & 835,69 & 0 & 0 & 2 \\ \hline 105 & 253,90 & 2 & 1 & 1 & 63531,5 & 2 & 668,55 & 0 & 0 & 1 \\ \hline 106 & 177,13 & 3 & 1 & 1 & 15658,63 & 2 & 835,69 & 0 & 0 & 2 \\ \hline 107 & 104,61 & 3 & 1 & 0 & 38829,04 & 3 & 835,69 & 0 & 1 & 2 \\ \hline 108 & 108,82 & 5 & 1 & 1 & 10064,97 & 2 & 1499,58 & 0 & 0 & 3 \\ \hline 109 & 145,71 & 4 & 1 & 1 & 17887,5 & 3 & 543,2 & 1 & 1 & 2 \\ \hline 110 & 299,11 & 4 & 1 & 1 & 17744,02 & 2 & 668,55 & 0 & 0 & 2 \\ \hline 111 & 131,28 & 3 & 1 & 1 & 31389,15 & 2 & 1253,53 & 0 & 0 & 2 \\ \hline & & & & & & & & & & \\ \hline \end{tabular}
