Exam 19: Data Analysis: Analyzing Individual Variables and Basics of Hypothesis Testing

The FactFinder Research firm conducted a survey for a national food manufacturer and one of the issues addressed by the research was to determine how many pounds of fish were annually consumed per capita.In the survey they found one person who consumed only one pound of fish per year while 10 people reported 200 pounds per year.The range was
