The Hill of Tara is located in south-central Meath, not far from Dublin, Ireland. Tara is of great cultural and archaeological importance, since it is by legend the seat of the ancient high kings of Ireland. For more information, see Tara: An Archaeological Survey, by Conor Newman, Royal Irish Academy, Dublin. Magnetic surveying is one technique used by archaeologists to determine anomalies arising from variations in magnetic susceptibility. Unusual changes in magnetic susceptibility might (or might not) indicate an important archaeological discovery. Let x be a random variable that represents a magnetic susceptibility (MS) reading for a randomly chosen site on the Hill of Tara. A random sample of 120 sites gave the readings shown in the table below. Magnetic Susceptibility Readings, centimeter-gram-second 106 (cmg 106) Magnetic Susceptibility 0x 10 10 < x < 20 30/120 = 0.25 54 54/120 0.45 0.15 18 18/120 20 < x < 30 30 < x < 40 "very interesting" 12 12/120 0.10 "hot spot" 40 x 6 6/120 0.05 What is a statistical experiment? How could the magnetic susceptibility intervals 0 < x < 10, 10 x < 20, and so on, be considered events in the sample space of all possible readings?
