Use dataset "HT_4143.xls" and conduct a two-sample t-test using Excel. You'd like to test the null hypothesis that the means of the two samples (column A and column B) are the same. The alternative hypothesis is that they are not the same. You have no reason to believe that the standard deviations of the two samples are equal.  Test at the alpha = 0.10 level.   After using Excel, what do you conclude? Are the means the same? Group of answer choices You reject the null hypothesis. Therefore, you conclude that the means of the two populations are different. You reject the null hypothesis. Therefore, you conclude that the means of the two populations are the same. You cannot reject the null hypothesis. Therefore, you conclude that the means of the two populations are different. You cannot reject the null hypothesis. Therefore, you conclude that the means of the two populations are the same.   HT_ 4143.xls: X1          X2 99.73     98.69 95.93     98.94 94.92     96.63 100.52   99.16 101.28   94.93 99.79     101.97 97.92      98.75 97.71     100.72 100.82    102.75 99.78      101.34 95.87      99.16 100.21    98.96 105.68    102.69 100.32     94.37 101.22    96.88 98.74     104.39 102.65    105.40 101.73    92.90 101.39     94.82 95.42      101.30 98.94      92.52 99.71     102.13 101.63    100.54 100.34    96.12 98.11     106.75 103.37    106.21 102.47    107.57 95.41      104.52 97.05     105.75 99.97     103.88 94.06     105.75 101.14   100.95 99.73     97.73 100.53   101.23 104.39    101.01 104.09    92.38 104.29    102.55 97.81      97.22 100.83    101.19 104.12    104.25 97.69     106.09 100.55 104.76
