The archaeological site of Tara is more than 4000 years old. Tradition states that Tara was the seat of the high kings of Ireland. Because of it's archaeological importance, Tara has received extensive study (Reference: Tara: An Archaeological Survey by Conor Newman, Royal Irish Academy, Dublin). Suppose an archaeologist wants to estimate the density of ferromagnetic artifacts in the Tara region. For this purpose, a random sample of 55 plots, each of size 100 square meters, is used. The number of ferromagnetic artifacts for each plot is determined.(a) Identify the variable. number of samples per 100 square meters all ferromagnetic artifacts number of ferromagnetic artifacts per 100 square meters number of plots of 100 square meters(b) Is the variable quantitative or qualitative? both quantitative and qualitative qualitative quantitative neither quantitative nor qualitative(c) What is the implied population? all archaeological sites originating around 4000 years ago the 55 plots that were examined the entirety of Ireland the entire Tara region

a) The variable we are testing is the amount of ferromagnetic artifacts. They are contained in 100 square meter plots; this means the answer is the number of artifacts per 100 square meters.

b) Since we are dealing with measurements, this is a quantitative variable.

c) The study is of the entire Tara region; this means the population is the entire Tara region.
