Aeriment is designed to compare five different advertisements for a pen. Advertisement A greatly undersells the pen. Advertisement B slightly undersells the pen. AdvertisementC slightly oversells the pen. Advertisement D greatly oversells the pen. Advertisement E correctly states the pen. A sample of 30 adult respondents is randomly assigned to the five advertisements. After reading the advertisement, all respondents unknowingly receive the same pen to evaluate and are then asked to rate the pen from 1 to 7 (lowest to highest) on three characteristics. The combined scores of three ratings for the 30 respondents are in the data table. Complete parts (a) through (d) below. E Click on the icon to view the data table.
