The archeological site of Tara is more than 4000 years old. Tradition states that Tara was the seat of the high kings of Ireland. Because of its archeological importance, Tara has received extensive study (Reference: Tara: An Archeological survey by Conor Newman, Royal Irish Academy, Dublin). Suppose an archeologist 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.

number of plots

size of the plots

the density of artifacts

number of ferromagnetic artifacts per 100 square meters

number of plots as well as size of the plot

"55 plots, each of size 100 square meters" gives the first two bits of information and possibly the last, however, I don't see data to allow you to provide the remaining answers.

Have you left out some data?

It says to:

Identify the variable in the information here. Then it states the information provided above.

The variable is the density of artifacts.

To estimate the density of ferromagnetic artifacts in the Tara region, the archeologist used a random sample of 55 plots, each with a size of 100 square meters. The number of ferromagnetic artifacts was determined for each plot.

To calculate the density of artifacts, you need to know the total number of artifacts and the total area of the sampled plots.

1. Number of plots: The archeologist used a random sample of 55 plots. This is the number of individual areas surveyed.

2. Size of the plots: Each plot has a size of 100 square meters. This is the area covered by each individual plot.

3. Number of ferromagnetic artifacts per 100 square meters: The number of artifacts found in each plot is determined. This gives you the number of artifacts per unit area.

To estimate the density of artifacts in the Tara region, you can calculate the total number of artifacts and divide it by the total area surveyed.

Total number of artifacts = (Number of ferromagnetic artifacts per 100 square meters) * (Number of plots) * (Size of the plots / 100)

Density of artifacts = Total number of artifacts / Total area surveyed

By plugging in the values obtained from the survey, you can calculate the estimated density of ferromagnetic artifacts in the Tara region.
