Solved: Cesium atoms cooled by laser light could be used
Chapter , Problem 106SE(choose chapter or problem)
Cesium atoms cooled by laser light could be used to build inexpensive atomic clocks. In a study reported in IEEE Transactions on Instrumentation and Measurement (2001, Vol. 50, pp. 1224–1228), the number of atoms cooled by lasers of various powers were counted. The data are in Table E11-19.
(a) Graph the data and fit a regression line to predict the number of atoms from laser power. Comment on the adequacy of a linear model.
(b) Is there a significant regression at \(\alpha=0.05\)? What is the \(P-\text { value }\)?
(c) Estimate the correlation coefficient.
(d) Test the hypothesis that \(\rho=0 \) against the alternative \(\rho \neq 0\) with \(\alpha=0.05\). What is the \(P-\text { value }\)?
(e) Compute a \(95 \%\) confidence interval for the slope coefficient.
