GBU 3311 02 Case Problem 3Selecting a Point-and-Shoot Digital CameraConsumer Reportstested 166 different point-and-shoot digital cameras. Based upon factors suchas the number of megapixels, weight (oz.), image quality, and ease of use, they developed anoverall score for each camera tested. The overall score ranges from 0 to 100, with higher scoresindicating better overall test results. Selecting a camera with many options can be a difficultprocess, and price is certainly a key issue for most consumers. By spending more, will aconsumer really get a superior camera? And, do cameras that have more megapixels, a factoroften considered to be a good measure of picture quality, cost more than cameras with fewermegapixels? Table 14.13shows the brand, average retail price (\$), number of megapixels, weight(oz.), and the overall score for 13 Canon and 15 Nikon subcompact cameras tested by ConsumerReports(Consumer Reportswebsite, February 7, 2012).Question 1: Develop numerical summaries of the data.
