(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 seven potential packages and allocate values to them to reflect their

ease of use and available facilities. These values are shown below (0 = worst, 100 = best).

package	ease of use	facilities available
super quill	100	30
easywrite	90	70
woodright	50	20
lexico	0	40
ultraword	20	100
keywrite	40	0
fastwrite	85	55

(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?

(c) After some reflection you realize that the extra facilities available on a package will be of little value to you if they are going to be difficult to use. What does this imply about your method of analysis in (b)?
