- Hearing A researcher investigated four different wordlists for use in hearing assessment. She wanted to knowwhether the lists were equally difficult to understand inthe presence of a noisy background. To find out, she tested 96 subjects with normal hearing randomly assign-ing 24 to each of the four word lists and measured the number of words perceived correctly in the presence ofbackground noise. Here are the boxplots of the four lists: ANOVA Table Source DFSum ofSquaresMeanSquare F-Ratio P-ValueList 3 920.4583 306.819 4.9192 0.0033Error 92 5738.1667 62.371Total 95 6658.6250a) What are the null and alternative hypotheses?b) What do you conclude?c) Would it be appropriate to run a multiple comparisonstest (for example, a Bonferroni test) to see whichlists differ from each other in terms of mean percentcorrect?
