Measurements of the weights are taken on a number of patients before and after an extensive exercise course. We will conduct both paired and unpaired means comparison test at 5% level (although paired is the correct one here) The computer output for both designs is given below. What are the parameters, statistic, and p-value for the UNpaired (Independent) design? diff C-Test: Paired Two Sample for Means Test: Two-Sample Assuming Equal Variances Median Mean 105 Weight Weight2 Weight Weght2 Standard Error 4.022259 Mean 169.625 159 125 Mean 169.626 159. 125 8.5 Variance 65.125 162 4107 Variance 65 125 162.4107 Mode NA Observations Observations Standard Deviation 11.37667 Pearson Correlation 0.476968 Pooled Variance 113 7679 Sample Variance 129.4286 Hypothesized Mean Hypothes.zed Mean Kurtosis 002468 of Skewness 0.5728 Stat 2 610473 t Stat 1968836 Range 35 Piet) oneta0 017445 PTC) one-tal 0034547 Minimum 6 Critical one 1894579 Critical one-tail 1.76131 Maximum 29 Piet) two- 0014889 Pret) two-tail 0069095 84 Critical two-ta 24524 Cricato al 7 144787 door 10.5, - 11.30, t - 2.61, tort - 1.89, p-val - 0.017 Xlbar-16962, X2bar -159.12, S1^2-65.12, 52-2-162.41, Sp^2-113.77, t - 1.97, tcrit-1.76, p-val - 0.035 Psi 169.62, Ps2 - 159.12, 51^2-65.12, 52^2-162.41, Phar-113.77, t - 1.97, terit-1.76, p-val -0.035 dbar- 10.5, -11.30, t - 2.61, terit - 2.36, p-val - 0.035 Xibar 169.62, XZbar-159.12, 51^2-65.12, 52^2-162.41, Sp^2-113.77, t - 1.97, terit-2.14, p.val - 0.069 Sum

Hi, See the data set below. Based on this, Excel comes with the following analysis (paired difference). I need to calculate a 95% confidence interval. Based on this, I came to the following formula: [Mean of the difference (D-mean) +/ t(alpha/2) * Sd / sqrt(n)]. I can fill in the following information: D-mean = 27-34 = -7. t(alpha/2) = 2,262 sqrt(n) = sqrt(10) Do you now how I can find the standard deviation of the sample? (Sd) I think it...
