II. A survey of CPAs across the United States found that the average net income for sole-proprietor CPAs is $98,500. Because this survey is over two decades old, an accounting analyst wants to test this figure by taking a random sample of 112 sole-proprietor accountants in the United States to determine whether the net income figure has changed or not. It is assumed that the population standard deviation of net incomes for sole-proprietor CPAs is $14,530. 7. Summarize the hypothesis for this test. (what is the hypothesis test?) 8. What is the critical value? 9. Using $\alpha = .05$, What is the critical value? 10. Using the same $\alpha$, report p-value. 11. What is your decision about the test? 12. What is 95% confidence Interval for the test?

Consider a prism made of N-BK7 glass. As with other types of glass, the index of refraction depends on the wavelength of the incident light. This is called dispersion which leads to a separation of colors as shown in the figure below. The dependence of the index of refraction on the wavelength is shown in the graph below. What is the angular dispersion of visible light passing through a prism of apex angle 60.0$^{\circ}$ if the angle of incidence is 50.0$^{\circ}$? (Recall that red light is near 700 nm and violet light is near 400 nm.) (Also note that you are looking at the angular dispersion after completely passing through both surfaces of the prism.)
