At an assembly plant that produces computer chips, each worker is responsible for the entire as- sembly of a chip. The production manager would like to compare the workers productivity (the number of chips produced per month) in two different work environments, A and B. A group of 25 experienced workers is selected at random and placed in environment A for a month and the sample mean number of chips produced is determined. The same 25 workers are then placed in environment B for a month and again the sample mean number of chips produced is determined. The manager would then like to use these results to determine if there is statistically significant evidence that the population mean number of chips is different for these two working environments. The results are given as follows: $\bar{x}_A$ = 150.2 chips; $\bar{x}_B$ = 154.3 chips (i.e. $\bar{x}_d$ = $\bar{x}_A$ - $\bar{x}_B$ = -4.1); $s_d$ = 10.5 chips. Q5. Determine a 95% confidence interval for the difference in the population mean number of chips ($\mu_A$ - $\mu_B$) produced in each environment. (Round your answer to 1 decimal place.) A. [-25.8, 17.6] B. [-8.4, 0.2] C. [-5.0, -3.3] D. [-0.2, 8.4] E. [-14.6, 6.4] Q6. Suppose that a 98% confidence interval for $\mu_A$ - $\mu_B$ is [-9.3, 1.1]. Which of the following is an appropriate interpretation of this result? A. There is statistically significant evidence that the two population means are different B. There is only a 2% chance that the difference in the two population means is outside of this interval C. We have not observed a statistically significant difference in the two sample means D. This is a statistically significant result indicating that $\mu_B$ > $\mu_A$ E. Based on this result, we should conclude that $\mu_A$ = $\mu_B$

(3) Let $C^\infty(\mathbb{R})$ denote the vector space consisting of infinitely differentiable functions $\mathbb{R} \to \mathbb{R}$, and consider the second-derivative operator $\frac{d^2}{dx^2} : C^\infty(\mathbb{R}) \to C^\infty(\mathbb{R})$. (a) Show that $\frac{d^2}{dx^2}$ is a linear map. (b) Let $a$ be a real number. Show that $f(x) = \cos(ax)$ and $g(x) = \sin(ax)$ are eigenvectors of $\frac{d^2}{dx^2}$ and compute their eigenvalues. (c) Let $a$ be a real number. Show that $h(x) = e^{ax}$ is an eigenvector of $\frac{d^2}{dx^2}$ and compute its eigenvalue.
