Aregression of average weekly earnings (awe, measured in dollars) on years age (measured in years) using a random sample of college-educated full- time workers aged 25-65 yields the following: awe 696.7+9.6 x age, r'-0.023, ser 624.1.
a. explain what the coefficient values 696.7 and 9.6 mean.
c. the regression r2 is 0.023. what are the units of measurement for the
d. what is the regression's predicted earnings for a 25-year-old worker?
e. will the regression give reliable predictions for a 99-year-old worker?
f. given what you know about the distribution of earnings, do you think of measurement for the ser? (dollars? years? or is ser unit-free? ) r2? (doliars? years? or is r2 unit-free? ) a 45-year-old worker? why or why not? it is plausible that the distribution of errors in the regression is nor- mal? (hint: do you think that the distribution is symmetric or skewed? what is the smallest value of earnings, and is it consistent with a normal distribution? ) g. the average age in this sample is 41.6 years. what is the average value of awe in the sample? (hint: review key concept 4.2.)

David burdick is the ceo of acme bubblegum, a successful public company. as one of the cofounders of the company, burdick has enjoyed speaking and writing about the success of acme bubblegum for several years. typically, he speaks at conferences or directly to the press, but recently, he has been blogging about his firm anonymously. specifically, he defended a recent advertising campaign that was unpopular among consumers and pointedly attacked one of acme bubblegum’s competitors. burdick deeply enjoys his anonymous blogging and believes that none of his readers actually know that he works for acme bubblegum. should burdick be allowed to praise his company’s performance anonymously online? should he be allowed to attack his competitors without disclosing his relationship with the company? how would you feel if the ceo of a company at which you shopped was secretly writing criticisms of his or her competition? how would you feel if you knew a writer for your favorite blog was actually closely involved in a company that the blog discussed? 1. define the ethical issue? 2. who are the primary stakeholders? 3. what are the possible alternatives? 4. how could you evaluate the ethical implications of the alternative actions (use appropriate decision rules)? 5. what action would you recommend and why?
