(1) True or false? The population regression function contains information on slope, intercept and the residuals. These are identical to those estimates obtained in random samples.

Question 1 Example of non-linear in parameters is: O 1V= o+1x O 3" I30 =118(x) O 1V= o+1x2 0 none of the above For the equation: salary = 831.59 + 92.16 roe, where "salary" is the CEO's salary in thousands of dollars and "roe" is return on equity of the CEO's firm. The sample collects the salary information of only those CEOs whose firms have a market capitalization of more than 100 million dollars. Is this sample random? Yes, it contains information on CEOs whose salary is determined independently O No, this sample contains information on companies that are already mature O can't be determinedTrue or False? In the regression model: salary = 30 + 51 roe +u where \"salary" is the CEO's salary in thousands of dollars and \"roe" is return on equity of the CEO's rm, a truly random sample is a collection of salaries and roe of companies of all sizes and across different geographical regions of the country under study. O True O False Two different values of the independent variable in the sample strictly ensures that: SST >0 O SST,
