3. Below is the formula for the Standard Score (or z-score) version of the linear regression model. Zy':B0+lgg In this equation, the regression coefficient is denoted as [3, which is the symbol for the Greek letter "beta\". [3 is the symbol for the greek letter \"beta\". Provide the correct interpretation of the following \"standardized\" regression coefficient: [3 = 1.5. 4. In linear regression, the F-test for the regression model is calculated as: [MS F _ regression Wmm If the obtained F-test is greater than the critical F-test then what should the researcher conclude? Would the regression model be considered \"statistically significant"? If "yes\" then how would one interpret such a statistically significant regression model? 5. The potential significance of a regression coefficient is evaluated by conducting a t-test. As discussed in the lecturer-naterial, the formula is "t = b / SEb\\f
