Compute the eigenvalues

7 Let A: -2 2 4 1. Compute the eigenvalues for A (list repeated eigenvalues only once) eigenvalue 1 = ; eigenvalue 2 = 2. Find an orthogonal matrix Q that will diagonalize A Q = Preview 3. And compute the spectral decomposition of A A =What is the difference between univariate data and bivariate data? Choose the correct answer below. 0 A. In univariate data, a single variable is measured on each individual. In bivariate data, two variables are measured on each individual. 0 B. In univariate data, there are only positive values and zeros. In bivariate data, there are positive values, negative values, and zeros. O C. In univariate data, there is one mean. In bivariate data, there are two means. 0 D. In univariate data, the data are qualitative. In bivariate data, the data are quantitative. Model: a right triangle. base and height can be modified. Three different views of triangle. View one displays lengths of sides. View two displays triangle graphically. View three logs changes in triangle state to file. A controller for view one, to modify triangle. No controller for other views.2. (10 points)(The Weak Law of Large Numbers) In order to estimate 3", the true fraction of smokers in a large population, Alvin selects u. people at random. His estimator Mn is obtained by dividing S", the number of smokers in his sample, by N, i.e., Mn = \"/11. Alvin chooses the sample size n to be the smallest possible number for which the Chebyshev inequality yields a guarantee that PiIMnfl 2 6) 5: where E and 6 are some prespeeied tolerances. Determine how the value of 11 recommended by the Chebyshev inequality changes in the following cases. (a) (5 points] The value of e is reduced to half its original value. (b) (5 points] The value of 5 is reduced to half its original value
