The population of air quality data was randomly divided into 40 samples or groups of readings with GroupID=1... GroupID=40 and each group has $n = 2696$ readings. The population mean of the PM2.5 readings across all 107 840 readings is 3.976 and the variance is 18.460. i) What is the approximate distribution of the sample mean for any of the 40 groups? ii) Recall, from TMA01, that the sample mean PM2.5 values for groups 2 and 40 are 3.762 and 3.976, respectively. Using Minitab, or otherwise, find the probabilities (to 2 significant figures) that: the sample mean PM2.5 value for any sample of size 2696 is less than 3.762. the sample mean PM2.5 value for any sample of size 2696 is less than 3.976.

5. Use the Laplace Transform to solve the boundary value problem. \begin{align*} 16 \frac{\partial^2 u}{\partial x^2} - 4 \frac{\partial^2 u}{\partial t^2} &= 0, \quad x > 0, \quad t > 0 \\ u(0, t) &= 0, \quad \lim_{x \to \infty} \frac{\partial u}{\partial x} = 0, \quad t > 0 \\ u(x, 0) &= 0, \quad \frac{\partial u}{\partial t}|_{t=0} = 0, \quad x > 0 \end{align*}

It is desired to design a model-based nonlinear controller for the RP manipulator shown in Figure 1. (a) Using a Lagrangian approach, derive the equations of motion of the RP manipulator, and find its mass matrix $M(q)$, where $q = [\theta_1, d_2]^T$. (b) Assuming perfect knowledge of the kinematic and dynamic properties of the manipulator, and zero joint disturbances, design a nonlinear controller, which can achieve zero steady state tracking error, $E_{ss}$. The error equation should not depend on q. Draw a block diagram showing the structure of your controller. (c) Assume that the worst constant joint disturbance vector is $\tau_d = [\tau_d^1, f_d^2]^T$. Pick-up the feedback gains of your controller so as to ensure that the error dynamics are critically damped, and that the max tracking error $E$ at the steady state does not exceed $E_{ss,max}$
