Create class Rectangle. The class has attributes length and width, each of which defaults to 0.0. It has properties for both length and width. The set accessors should verify that length and width are each floating-point numbers greater than 0.0 and less than 20.0. It has read-only properties that calculate the Perimeter and the Area of the rectangle. Write an app to test class Rectangle.

A researcher was interested in comparing the amount of time spent watching television by women and by men. Independent simple random samples of 14 women and 17 men were selected, and each person was asked how many hours he or she had watched television during the previous week. The summary statistics are as follows. Sample-1 Women Sample-2 Men n1 = 14 n2 = 17 $\bar{x}_1$ = 12.6 hrs $\bar{x}_2$ = 14.0 hrs $s_1$ = 3.9 hrs $s_2$ = 5.2 hrs Find the value of the Test statistic (T.S.) for this hypothesis test. Hints: T.S. = $t = \frac{\bar{x}_1 - \bar{x}_2}{\sqrt{\frac{s_1^2}{n_1} + \frac{s_2^2}{n_2}}}$ $\circ$ 5.23 $\circ$ .856 $\circ$ -.856 $\circ$ -5.23

Fourier Series: Problem 5 Previous Problem Problem List Next Problem (1 point) Note: The notation $F_n(x)$ represents the $n$th partial sum, which can also be denoted as $S_n(x)$. Note: Use parentheses when appropriate. For example, \"sin 2x\" will be read by WeBWork as \"sin(2) * x\" . Construct the first three Fourier approximations to the square wave function $f(x) = \begin{cases} 1 & -\pi \le x < -\frac{\pi}{2} \\ -1 & -\frac{\pi}{2} \le x < \frac{\pi}{2} \\ 1 & \frac{\pi}{2} \le x < \pi \end{cases}$ F?(x) = F?(x) = F?(x) = Using a calculator, graph the function and the first three Fourier approximations to see how the approximation matches the function f(x).
