Consumer Reports tested different point-and-shoot digital cameras. Based upon factors such as the number of megapixels, weight (), image quality, and ease of use, they developed an overall score for each camera tested. The overall score ranges from to , with higher scores indicating better overall test results. Selecting a camera with many options can be a difficult process, and price is certainly a key issue for most consumers. By spending more, will a consumer really get a superior camera? And, do cameras that have more megapixels, a factor often considered to be a good measure of picture quality, cost more than cameras with fewer megapixels? Table 14.13 shows the brand, average retail price (), number of megapixels, weight (), and the overall score for Canon and Nikon subcompact cameras tested by Consumer Reports (Consumer Reports website, February 7, 2012).

Question

Consumer Reports tested different point-and-shoot digital cameras. Based upon factors such as the number of megapixels, weight (), image quality, and ease of use, they developed an overall score for each camera tested. The overall score ranges from to , with higher scores indicating better overall test results. Selecting a camera with many options can be a difficult process, and price is certainly a key issue for most consumers. By spending more, will a consumer really get a superior camera? And, do cameras that have more megapixels, a factor often considered to be a good measure of picture quality, cost more than cameras with fewer megapixels? Table 14.13 shows the brand, average retail price (), number of megapixels, weight (), and the overall score for Canon and Nikon subcompact cameras tested by Consumer Reports (Consumer Reports website, February 7, 2012).

Answer - Part 4 of the question

Managerial Report
1. Develop numerical summaries of the data.
2. Using overall score as the dependent variable, develop
three scatter diagrams, one using price as the independent
variable, one using the number of megapixels as the
independent variable, and one using weight as the
independent variable. Which of the three independent
variables appears to be the best predictor of overall score?
3. Using simple linear regression, develop an estimated
regression equation that could be used to predict the overall
score given the price of the camera. For this estimated
regression equation, perform an analysis of the residuals
and discuss your findings and conclusions.
4. Analyze the data using only the observations for the
Canon cameras. Discuss the appropriateness of using simple
linear regression and make any recommendations regarding
the prediction of overall score using just the price of the
camera.
