A researcher wants to determine if there is a difference in mean insertion times for a laryngeal mask airway (LMA) or king airway (KA) by PAs that work in an emergency department. 100 subjects participated in the study. Each subject performed insertion of the LMA and the KA. If there was a normal distribution in the data (bell shaped curve) and there were equal variances, what inferential statistical test should be used?
