The probability that any one battery will be defective is 0.2. Once every week, two batteries are randomly selected from the production line. The table below shows the number of weeks in which 0, 1, and 2 batteries were defective and thus thrown away in 2021. Propose an appropriate probability distribution for the number of defective batteries and test to see if it is consistent with the data observed. Use the Chi-Square test with a significance level of 0.01. Number of Batteries Thrown Away | Number of Weeks --------------------------------|---------------- 0 | 12 1 | 24 2 | 16

7. [Total: 20 pts] Consider the screened Coulomb potential of a point charge $q$ that arises e.g. in plasma physics: $V(r) = \frac{q}{4\pi\epsilon_o} \frac{exp(-r/\lambda)}{r}$, where $\lambda$ is a constant called screening length. a) Determine $\mathbf{E}(r)$ associated with potential. b) Find the charge distribution $\rho(r)$ that produces this potential. (Think carefully about what happens at the origin!) c) Show by explicit integration over $\rho(r)$ that the charge represented by this distribution is zero. (If you don't get zero, think again about what happens at $r = 0$). d) Verify your result from part c) by using Gauss's Law.
