An accounting professor is notorious for being stingy in giving out good letter grades. In a large section of 130 students in the fall semester, she gave out only 5% A's, 28% B's, 38% C's, and 29% D's and F's. Assuming that this was a representative class, compute the 95% confidence interval of the probability of getting at least a B from this professor.

void start(); void accelerate(double speed); void stop(); double get_speed() const; private: double speed1; }; Car::Car() { speed1 = 0; } #endif Which of the following is true about placing the function definition Car::Car() in the header file? C Function definitions cannot be enclosed within header files. It will result in a compilation error. Function definitions should not be enclosed within header files. The header file may be included by multiple source files, which would cause the function to be compiled more than once. Function definitions must always be enclosed within the header files but not the source files. Function definitions must always be enclosed within the header files and the source files.

mean: 3.5i Measuring skewness: The skewness of a distribution can also be calculated using the formula: Median=3.4 Standard deviation 0.83 Skewness = \frac{3(mean - median)}{standard\ deviation} A perfect normal curve (bell-shaped) has skewness value of 0 while positive values indicate positive skewness (right-skewed) and negative values indicate negative skewness (left-skewed). Typically, values ranging between -0.5 to +0.5 indicate the distribution is approximately normal. Show how to calculate the skewness value of the unemployment rates and determine whether the data are approximately normal by using this measure. Round to 1 decimal place.

1- Determine the values of $K_p$ and $K_d$ of the closed-loop system shown in Fig. below so that the maximum overshoot in unit-step response is 28% and the peak time is 1.3 sec. Assume that J=3 kg-m², B=3 N-m_rad_sec. D R = 0 E T + $K_p + K_ds$ + + $\frac{1}{s(Js + b)}$ C 2- Find the steady-state error due to a unit step disturbance torque. Then, propose a controller that improves the steady-state error.
