Radon exposure in Egyptian tombs. Refer to the Radiation
Chapter 6, Problem 99E(choose chapter or problem)
Radon exposure in Egyptian tombs. Refer to the Radiation Protection Dosimetry (December 2010) study of radon exposure in tombs carved from limestone in the Egyptian Valley of Kings, Exercise 6.30 (p. 318). The radon levels in the inner chambers of a sample of 12 tombs were determined, yielding the following summary statistics: \(\bar{x}=3,643\ Bq/m^3\ \text{and}\ s=4,487\ Bq/m^3\). Use this information to estimate, with 95% confidence, the true standard deviation of radon levels in tombs in the Valley of Kings. Interpret the resulting interval.

QUESTION:
Radon exposure in Egyptian tombs. Refer to the Radiation Protection Dosimetry (December 2010) study of radon exposure in tombs carved from limestone in the Egyptian Valley of Kings, Exercise 6.30 (p. 318). The radon levels in the inner chambers of a sample of 12 tombs were determined, yielding the following summary statistics: \(\bar{x}=3,643\ Bq/m^3\ \text{and}\ s=4,487\ Bq/m^3\). Use this information to estimate, with 95% confidence, the true standard deviation of radon levels in tombs in the Valley of Kings. Interpret the resulting interval.
ANSWER:Solution:
Step 1 of 2:
It is given that in the study of tombs carved from the limestone, for 12 randomly selected toms the obtained statistics are =3,643Bq/
and s=4487Bq/
.
Using this information we need to find the 95% confidence interval for the true value of the standard deviation.
