Design a class called Student to represent a student, with private member variables for the student's ID and grade. Implement the following public member functions: 1. set_ID(string id): Sets the ID number of the student. 2. set_grade(string g): Sets the grade of the student. 3. get_ID(): Returns the ID number of the student. 4. get_grade(): Returns the grade of the student. In the main function: 1. Create an array of three Student objects. 2. Prompt the user to input the ID number and grade for each student. 3. Use the appropriate member functions (set_ID and set_grade) to set the ID and grade for each student. 4. After setting the values, display the ID and grade for each student using the get_ID and get_grade functions.

A particular study investigated the use of punishment in cooperation games. In the study, college students repeatedly played a version of the game "prisoner's dilemma," and the researchers recorded the average payoff and the number of times cooperation, defection, and punishment were used for each player. Complete parts a through c below using a significance level of alphaαequals=0.100.10. Question content area bottom Part 1 a. Give the null and alternative hypotheses for testing whether average payoff and punishment use are nothingcorrelatedcorrelated.

Nolong dash—a causal relationship cannot be inferred on the basis of high sample correlation. B. Yeslong dash—a causal relationship may be inferred on the basis of the low p-value. C. The inference depends on the result of the corresponding regression analysis. D. The inference depends on the magnitude of the sample correlation coefficient. If its absolute value is greater than 0.9, then a causal relationship can be inferred.

3. ( 15 points) Consider a fixed-free bar of a uniform cross-sectional area $ A $, a length $ l $, a modulus of elasticity $ E $, and a mass density $ \rho $. Find the longitudinal vibration response of the bar subjected to the following initial conditions \[ \begin{array}{c} u(x, 0)=U_{0} x^{2} \quad \text { and } \quad \frac{\partial u}{\partial t}(x, 0)=0 \\ {\left[A n s: u(x, t)=-\frac{16 U_{0} l^{2}}{\pi^{3}} \sum_{n=1,2, \ldots}^{\infty} \frac{(-1)^{n} \pi(2 n-1)+2}{(2 n-1)^{3}} \sin \left(\frac{(2 n-1) \pi x}{2 t}\right) \cos \left(\frac{(2 n-1) \pi c t}{2 t}\right)\right] .} \end{array} \]

3- Which of the following statements is false ? a) If $f: \mathbb{C} \to \mathbb{C}$ is the function defined by $f(z) = 3z^4 + z$, then the maximum value of $|f(z)|$ on the region $D = \{z \in \mathbb{C} : |z| \le 3\}$ occurs on the circle $|z| = 3$. b) 0 is an isolated singular point of the complex valued function $f(z) = \frac{1}{\sin(\frac{1}{z})}$ c) The radius of convergence of the power series $\sum_{n=1}^{\infty} \frac{(z+i)^n}{3^n(3n-1)^2}$ is 3. d) $S = \{z \in \mathbb{C} : 0 < |z + 2i| < 3\}$ is a multiply connected domain in the complex plane. e) If a complex valued function $f(z)$ is entire, then $f'(z)$ is also entire.
