A researcher wants to compare whether scores between two rugby teams are significantly different. For the first team, their mean score across 30 games is 12.4 , with a standard deviation of 2.5 . For the second team, their mean score is 10.9 across 22 games, with a standard deviation of 4.6 . Given \( a=0.05 \), what is the correct decision?
Reject HO 0 p is less than 0.5
Do not reject HO p is less than 0.5
Reject \( \mathrm{H} \sim 0 \mathrm{p} \) is more than 0.5
Do not reject HO 0 p is more than 0.5
