A researcher found that sales oftelevisions and lawn fertilizer have beenincreasing over the past 12 years. Thesales had a strong positive linearcorrelation, but no evidence could befound to support a cause-and-effectrelationship. Rather, this would have beenpurely coincidental. This is an example ofa)an accidental cause-and-effectrelationshipb)a cause-and-effect relationshipO ca reverse cause-and-effectrelationshipOa presumed cause-and-effectd)relationship

Substitute the values you found in steps 1 and 2 into the equation for the regression line to find the estimated linear model.

** Based on the regression results, answer the following questions ** A sample of data is collected (from 1999 and 2000) concerning the compensation of the executives (compensation is measured in 1000’s of $’s) of a number of public companies along with other firm-specific data. The dependent variable is total compensation, CEOANN is a dummy variable =1 for an individual who is a CEO and =0 for individuals who are not CEO’s, EMPL is total employees, MKTVAL is the natural logarithm of the market value of the firm, EPSIN is earnings per share, YEAR is a dummy variable = 1 for the year 2000 and =0 for year 1999, and ASSETS is the natural logarithm of the total assets of the company.

A study tests the effect of earning a Master's degree on the salaries of professionals. Suppose that the salaries of the professionals (S,) are not dependent on any other variables. Let D, be a variable which takes the value 0 if an individual has not earned a Master's degree, and a value 1 if they have earned a Master's degree.
