You have a cold gas of gold atoms, and you observe that if you shine light consisting of photons with energy 10.2 eV through the gas, some free electrons are observed, implying that a photon of this energy is able to ionize an atom in the gas. You find that the emitted electrons have a kinetic energy of 1.0 eV. What is the ionization energy of the gold atom? What is its ground state energy K + U? you shine...

Suppose you are working for a regional residential natural gas utility. For a sample of 90 customer visits, the staff time per reported gas leak has a mean of 211 minutes and standard deviation 31 minutes. The VP of network maintenance hypothesizes that the average staff time devoted to reported gas leaks is 219 minutes. At a 10 percent level of significance, what is the lower bound of the interval for determining whether to accept or reject the VP's hypothesis?...
