Companies that recently developed newproducts were asked to rate which activities are most difficult toaccomplish with new products. Options included such activities asassessing market potential, market testing, finalizing the design,developing a business plan, and the like.
A researcher wants to conduct asimilar study to compare the results between two industries: thecomputer hardware industry and the banking industry. He takes arandom sample of 64 computer firms and 89 banks. The researcherasks whether “market testing†is the most difficult activity toaccomplish in developing a new product. Forty-seven percent (47%)of the sampled computer companies and fifty-four percent (54%) ofthe banks respond that it is the most difficult activity. Use asignificance level of .20 to test whether there is a difference inthe responses to this question from these two industries.
