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 at an archaeological research location. A random sample of 120 sites gave the readings shown in the table below. Magnetic Susceptibility Readings, (cmg x 10-6) centimeter-gram-second × 10-6 Magnetic Susceptibility 0 < x < 10 Number of Estimated Comment "cool" Readings 24/120 : Probability 24 = 0.20 "neutral" "warm" "very interesting" "hot spot" 60/120 = 0.50 18/120 = 0.15 12/120 = 0.10 = 0.05 10 < x < 20 60 20 < x < 30 18 30 < x < 40 12 40 < x 6/120 Consider a binomial setting in which "neutral" is defined to be a success. So, p = binomial random variable that represents the number of "neutral" geomagnetic readings. P(success) = P(10 < x < 20). Suppose n = 45 geomagnetic readings are taken. Let r be a
