Question 4: Explain underlying difference between concept selection & concept testing processes and offer your comments on "after we have generated many concepts during concept generation process, why cannot we directly switch to concept testing through omitting concept selection)?" (05 Marks) Question 5: Assume that Hybrid cars are currently sold into this market at a rate of 200,000 units per year. Assume that the company sells the product through a single distributor that accounts for 30 percent of the sales in this category. Assume that results from a concept test with factory managers responsible for purchasing transportation devices indicate a definitely-would-buy fraction of 0.30 and probably would buy fraction of 0.20. If we use values of calibration constants of and probability as 0.4 and 0.2 respectively, then estimate the quantity of the hybrid cars expected to be sold during the time period. (05 Marks)
