Here are summary statistics for the weights of Pepsi in randomly selected cans: n=36, $\bar{x}$= 0.82406 lb, s= 0.00573 lb. Use a confidence level of 95% to complete parts (a) through (d) below. a. Identify the critical value $z_{\alpha/2}$ used for finding the margin of error. $z_{\alpha/2}$ = $\boxed{ }$ (Round to two decimal places as needed.) b. Find the margin of error. E = $\boxed{ }$ lb (Round to five decimal places as needed.) c. Find the confidence interval estimate of $\mu$. $\boxed{ }$ < $\mu$ < $\boxed{ }$ (Round to five decimal places as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. OA. There is a 95% chance that the true value of the population mean weight of Pepsi in a can will fall between the lower bound and the upper bound. OB. One has 95% confidence that the sample mean weight of Pepsi in a can is equal to the population mean weight of Pepsi in a can. OC. One has 95% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of Pepsi in a can. OD. Approximately 95% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound.

2. Define the indexed family of sets $A_i = \{x \in \mathbb{Z} \mid x \text{ is divisible by } i\}$ for $i = 2, 3, 4$. Determine $A_2 \cap A_3$ and explain its significance. 3. If Set $X = \{1, 2, 3\}$ and Set $Y = \{a, b\}$, find the Cartesian product $X \times Y$. Define a relation $R$ on $X \times Y$ where $(x, y) \in R$ if and only if 'x' is less than the ASCII value of 'y'. 4. Define an equivalence relation on the set of all integers. Provide an example and explain the properties that make it an equivalence relation.

a. Suppose $p(x) = a_0 + a_1x + \dots + a_{n-1}x^{n-1} + x^n$. The companion matrix of this polynomial is given by $\begin{bmatrix} 0 & 1 & 0 & \dots & 0 \\ 0 & 0 & 1 & \dots & 0 \\ \vdots & \vdots & \vdots & \ddots & \vdots \\ 0 & 0 & 0 & \dots & 1 \\ -a_0 & -a_1 & -a_2 & \dots & -a_{n-1} \end{bmatrix}$ (1) For the polynomials $p_2(x) = x^2 - 1$ and $p_3(x) = x^3 + 2x^2 + x - 1$, find the corresponding companion matrix and its characteristic polynomial (recall the characteristic polynomial of a matrix A is given by $f(\lambda) = |A - \lambda I|$). b. Show that the characteristic polynomial $f$ of the companion matrix of an $n$th degree polynomial satisfies $(-1)^n p(\lambda) = f(\lambda)$. Explain why the eigenvalues of $A_n$ coincide with the roots of $p$.
