Solved: Radon exposure in Egyptian tombs. Refer to the
Chapter 7, Problem 53E(choose chapter or problem)
Radon exposure in Egyptian tombs. Refer to the Radiation Protection Dosimetry (December 2010) study of radon exposure in Egyptian tombs, Exercise 6.30 (p. 318). The radon levels—measured in becquerels per cubic meter \(Bq/m^3\)—in the inner chambers of a sample of 12 tombs are listed in the table (next page). For the safety of the guards and visitors, the Egypt Tourism Authority (ETA) will temporarily close the tombs if the true mean level of radon exposure in the tombs rises to 6,000 \(Bq/m^3\). Consequently, the ETA wants to conduct a test to determine if the true mean level of radon exposure in the tombs is less than 6,000 \(Bq/m^3\), using a Type I error probability of .10. An SPSS analysis of the data is shown (bottom, p. 384). Specify all the elements of the test: \(H_0\), \(H_a\), test statistic, p-value, \(\alpha\), and your conclusion.
