3. Consider a test signal m(t) defined by a tangent hyperbolic function: $m(t) = A \tanh(\beta t)$ Where A and $\beta$ are constants. Determine the minimum step size $\Delta$ for delta modulation of this signal, which is required to avoid slope overload.

Suppose several students wish to determine if the course Virtual Desktop (VDI) is faster on Saturday than Sunday. Since the speed of the Virtual Desktop depends on internet speed, the same 50 students will test the Virtual Desktop on both Saturday night and Sunday night (where each student uses the same computer and wifi network on Sunday as they did on Saturday). These 50 students record how long (in minutes) it takes them to log into the Virtual Desktop, open R, import data, and compute one linear regression model. They import the same data set and compute the same linear regression model both nights. What method would they use to compare the average time spent to
