Out of 30 teams, 5 teams were shortlisted on several parameters. The top team will be that whose mean Average Handle Time (AHT) performance will be the least. You are given the AHT data of the five shortlisted teams. Before identifying the team with best AHT performance, you want to first check if there is a significant difference in AHT performance of at least one team. Since the data is normal and you want to identify the mean AHT performance, you perform a One-Way ANOVA. The alternative hypothesis is that the AHT performance of at least one team is significantly different. Based on the given analysis, select the correct conclusion from the choices.
