Question Help: Message instructor Submit Question Question 5 Suppose that you run a correlation and find the correlation coefficient is 0.291 and the regression equation is $\hat{y} = 3.9x - 14.54$. The mean values of your data were $\bar{x} = 7.6$ and $\bar{y} = 15.3$. If the critical value is .606, use the appropriate method to predict the $y$ value when $x$ is 6. 0/1 pt 4 19 Details Question Help: Message instructor Submit Question Question 6 You wish to determine whether there is a linear correlation (relationship) between the average monthly air

An ECG signal is often contaminated by baseline wander, which can be removed using a Moving Average (MA) filter. The filter is described by the following equation: $$ y(n) = \frac{1}{5} [x(n) + x(n - 1) + x(n - 2) + x(n - 3) + x(n - 4)] $$ Where: • $x(n)$ is the input ECG signal, • $y(n)$ is the filtered ECG signal. a) Draw the signal flow diagram for this filter. b) Find the impulse response $h(n)$ of the filter by letting $x(n) = \delta(n)$. c) Apply the z-transform on $y(n)$ and determine the transfer function $H(z)$ of this filter.
