Question

Which of the following is the most correct final results formula for this SPSS output (assume they used a two-tailed test, alpha \( =5 \%) \) : \begin{tabular}{|c|c|c|c|c|c|} \hline \multicolumn{6}{|c|}{Group Statistics} \\ \hline & birth_order & N & Mean & Std. Deviation & Std. Error Mean \\ \hline \multirow[t]{2}{*}{height} & first born & 9 & 68.4444 & 3.50397 & 1.16799 \\ \hline & youngest or middle & 11 & 65.0909 & 3.04810 & 91904 \\ \hline \end{tabular} Independent Samples Test \( t(18)=2.29, p=.034 \) \( t(16.05)=2.26, a<5 \% \) \( \mathrm{t}(18)=2.29, \mathrm{a}<5 \% \) \( t(16.05)=2.26, p=.038 \)

          Which of the following is the most correct final results formula for this SPSS output (assume they used a two-tailed test, alpha \( =5 \%) \) :
