2. Cognitive biases Boondocks Gumbo is a locally owned restaurant in Houston, Texas, with eight locations. The owner recently developed a new recipe for the restaurant’s signature gumbo dish. The owner decided to try out the dish in four of the company’s locations. After one month, the owner had gathered the following data: After looking over the data, the owner happily noted that the number of orders of the signature gumbo dish at the locations where the new recipe had been used (locations 1–4) had increased in comparison to the traditional number of orders of the dish (locations 5–8). The owner then decided to implement the new recipe at the rest of the company’s locations. a. Evaluate whether the owner made the correct decision. b. Identify which cognitive bias was likely at play in this situation, and describe how it occurred.

2. A solid insulating sphere has a spherical hole at its center. The outer radius of the sphere is $R_2$ and the inner radius of the sphere is $R_1$. The insulator has a uniformly distributed total charge of $Q_2$. At the very center of the hole is a point charge, $Q_1$. What is the magnitude of the electric field at a distance $r$ from the center for the regions $r < R_1$, $R_1 < r < R_2$ and $r > R_2$.

1. Let A be a symmetric matrix with eigenvalues $\lambda_1, \dots, \lambda_n$. It is known that there exists an orthogonal matrix C such that $A = CDC^\prime$, where $D = diag(\lambda_1, \dots, \lambda_n)$. Use this fact to prove the following: (a) $|A| = \lambda_1 \lambda_2 \dots \lambda_n$, where $|A|$ is the determinant of A. (b) $trace\{A\} = \lambda_1 + \lambda_2 + \dots + \lambda_n$.
