Z- transformation Questions

Q1: given a difference equation, how do we find unit step/ impulse response?

Q2: based on Q1, do we need to find transfer function to get output response y(z)= h(z)x(z)

Q3: is initial condition for input x(z) =0 or is it given
Example: y(z)+2z^-1 y(1) = x(z) +2zx(1) + x(0)

if given y(1) =1, and x(1) and x(0) not given
do we assume x(1) and x(0) =0?

please do these 2 problem step by step and how how you get z core SAT scores are normally distributed with a mean of 1,500 and a standard deviation of 300. An administrator at a college is interested in estimating the average SAT score of first-year students. If the administrator would like to limit the margin of error of the 86% confidence interval to 15 points, how many students should the administrator sample? Make sure to give a whole number...

When we do find a significant ANOVA, we do not know where the difference lies. It could be that only two groups are significantly different, or that all three groups are significantly different. In your response you mention that one problem with t-tests is that they only compare two groups at a time. This creates another problem with conducting multiple t-tests, which is that it increases our chances of committing a type I error. In what way do post-hoc tests...
