Individual Assignment \#1(2) You need a word-processing package for the personal computer in your office. Because your employer will pay for the package you are not concerned about the cost, but you would like a package which is as easy to use as possible and which also has a wide range of functions such as a thesaurus, spell checker and graphics. After discussing the matter with a friend who is something of an expert in this field, you identify several potential packages and allocate values to them to reflect their ease of use and available facilities. These values are shown (\(0=\) worst, 100\(=\) best)(a) Plot each package's value for 'ease of use' and 'facilities available' on a graph and hence determine the packages which lie on the efficient frontier.(b) Suppose that you judge that a switch from a package with the least facilities available to one with the most facilities is only \(60\%\) as attractive as a switch from a package which is the least easy to use to one which is the most easy to use. Assuming that mutual preference independence exists between the two attributes, which package should you choose?
