(Answered) Manufacturing and product development many comforters

Statistics

Manufacturing and Product Development Many comforters contain both white feathers and down in order to provide a warm, soft cover. A bed-and-bath company would like to expand its line of products and sell comforters for queen- and king-size beds. Before manufacturing begins, a random sample of comforters is obtained from other companies and the proportions of white feathers, down, and other components are measured and recorded. These data will be used to determine the exact mixture of feathers and down for the new line of comforters.

a. Is this an observational or an experimental study?

b. What are the variables of interest?

c. Describe a method for obtaining a random sample of comforters from current manufacturers.
