A researcher investigated the effect of different ambient room temperatures on working memory performance. Two groups of participants, teenagers (N=150N = 150N=150) and elderly individuals (N=150N = 150N=150), were asked to complete a digit span task under various controlled temperature conditions ranging from 15∘C15^\circ\text{C}15∘C to 33∘C33^\circ\text{C}33∘C.
The results are shown in Table 1 below.
