It is thought that prehistoric Indians did not take their best tools, pottery, and household items when they visited higher elevations for their summer camps. It is hypothesized that archaeological sites tend to lose their cultural identity and specific cultural affiliation as the elevation of the site increases. Let x be the elevation (in thousands of feet) of an archaeological site in the southwestern United States. Let y be the percentage of unidentified artifacts (no specific cultural affiliation) at a...

The following data
represent a company's yearly sales volume and its advertising
expenditure over a period of 8 years.
Develop a scatter diagram of
sales versus advertising and explain what it shows regarding the
relationship between sales and advertising. Make sure your axes are
labeled and that you have the axes correct (notice that x and y are
above the labels). The graph should have a title that mentions the
two variables.
