Consider a study to assess the readability of financial report messages. The effectiveness of the written message is assessed using a standard procedure. Financial reports were given to independent random samples from three groups—certified public accountants, chartered financial analysts, and commercial bank loan officer trainees. The procedure was then administered, and the scores for the sample members were recorded. The null hypothesis of interest is that the population mean scores for the three groups are identical.
