Symmetry matrix

6. ( 6 pts ) Consider the following symmetric matrix: 1 1 A=1 11 1 1 1 Compute the spectral decomposition of A = QAQwhere Q is an orthogonal matrix and A a diagonal matrix.A researcher is studying the effect of quality of work life and employee performance. As part of the procedure for data analysis, normality testing is required to be done and reported. The table below depicts the normality test results. Kolmogorov-Smirnov and Shapiro-Wilk have different analysis. What should the researcher do? Interpret and report the normality test for the two variables. Tests of Normality Kolmogorov-Smirnova
