The article “Feasting on Protein” (AARP Bulletin, September 2009) gave the cost per gram of protein for 19 common food sources of protein.
a. Construct a dotplot of the cost-per-gram data.
b. Locate the cost per gram for meat and poultry items in your dotplot and highlight them in a different color. Based on the dotplot, do meat and poultry items appear to be a good value? That is, do they appear to be relatively low cost compared to other sources of protein?
