Figure 18.11 Initial Analysis of the Final Laptop Design
The Effect Summary and Likelihood Ratio Tests outlines indicate that Disk Size, Speed, and Price are significant at the 0.05 level, and that Battery Life is marginally significant.

Move the slider for Price to $1,500.
Figure 18.13 Utility Profiler at Price = $1500
When Price changes from $1,000 to $1,500, the Utility changes from –0.3406 to –2.3303. That is, raising the price of a laptop by $500.00 lowers the utility (or desirability) approximately 2 units. Therefore, you can estimate the unit utility cost to be approximately $250.00.
Figure 18.14 Utility Value of Higher Speed
The Utility value changes from the original value shown in Figure 18.12 of –0.3406 to 0.9886, for a total change of 1.3292 units. Using the utility cost estimate or $250.00, the increase in price for a 2.0 GHz laptop over a 1.5 GHz laptop can be computed to be 1.3292*$250.00 = $332.30. This is the dollar value that the Choice study indicates that the manufacturer can use as a basis for pricing this laptop attribute. You can make similar calculations for the other attributes.
