SA 2 – (10 points) You will find the eigenvalues for A and also identify the multiplicity of each. Show all work and label the steps for full credit. This will be uploaded at the end of the exam. REWRITE the problem identifying which one it is.

Use a χ2 test of Association to test the claim that in the given contingency table, the row variable and the column variable are independent.  Be sure to identify and include in your answer the following: the null hypothesis, alternative hypothesis, expected values, test statistic, rejection region, conclusion about the null hypothesis, and a final conclusion that addresses the original claim that the two variables are independent (no relationship).  Note: you can use the equation editor to insert symbols and you must show some work as to how the expected values were calculated – if no work is shown full credit will not be given – you can use the insert table function to insert your work). Speeding and State of Residence: A researcher wants to see if there is a relationship between speeding and states of residence on Interstate 20/59 near Livingston, AL at the α = 0.05 level of significance. These data were collected:   Mississippi Alabama Speeders (71 mph or more) 18 25 Non-speeders (70 mph or less) 27 15

One of the eigenvalues of an autocorrelation matrix associated with the input of an FIR system identification system is zero / the rest of the eigenvalues are not zero. Theoretically, the identification will work as follows (using standard matrix solution methods)

The RLS FIR adaptive algorithm with time updates is approximately closer to the
