For the knowledgeable consumer, which attribute(s) need improvement?

Imagine you work for a well-known market research firm. Your supervisor has asked you to calculate numerical values for consumer attitudes using the Fishbein expectancy-value model, A = Σbe.
In your preliminary research for a client that manufacturers LCD HDTVs, you learned that the key attributes are picture resolution, screen size, viewing angles, reliability, and easy-to-use inputs. Using the data below, compute attitude scores for consumer A, a highly knowledgeable consumer, and for consumer B, a consumer who knows relatively little about HDTVs.
