5.63. A quality control engineer inspects a random sample of two hand-held calculators from each incoming lot of size 18 and accepts the lot if they are both in good working condition; otherwise, the entire lot is inspected with the cost charged to the vendor. What are the probabilities that such a lot will be accepted without further inspection if it contains 4 calculators that are not in good working condition; 8 calculators that are not in good working condition; 12 calculators that are not in good working condition?

Are you smarter than a second grader? A random sample of 65 second graders in a certain school district are given a standardized mathematics skills test. The sample mean score is $\bar{x} = 53$. Assume the standard deviation of test scores is $\sigma = 15$. The nationwide average score on this test is 50. The school superintendent wants to know whether the second graders in her school district have greater math skills than the nationwide average. Use the $\alpha = 0.10$ level of significance and the $P$-value method with the TI-84 Plus calculator. Part: 0 / 5 Part 1 of 5 (a) State the appropriate null and alternate hypotheses. $H_0:$ $H_1:$ This hypothesis test is a (Choose one) test.
By using Gauss' Law, compute for the electric field inside and outside a spherical shell of a charge with radius R and surface charge density sigma _(). What does your formula give in the limit that you are outside the sphere with r>>R? Comment on the result.
2. Use mathematical induction to show that if \(\lambda\) is an eigenvalue of an \(n \times n\) matrix \(A\), with \(x\) a corresponding eigenvector, then, for each positive integer \(m\), \(\lambda^m\) is an eigenvalue of \(A^m\), with \(x\) a corresponding eigenvector. (15 points)
