catter Plot, simple regression line re: the amount of tar having an effect on the amount of nicotine in cigarettes. Mainly.... the data set shows tar levels ranging from 1mg - 17mg, with an additional data point of 29..8mg - it remains on the regression line. My questions come from the 'appropriateness' questions..
x=0, y intercept is 0.131mg - 0 mg is below the data set so inappropriate? OR Appropriate because still plausible that a cigarette with NO tar could still have 0.131 mg of nicotine.
Then...for the appropriateness of 25mg... if using the top level of the data set of 29.8mg then yes, it is appropriate as still within the parameters of the data set OR no, because 29.8mg is considered an outlier?
.... I have read the book, read our notes, etc (online class) and watched videos but nothing REALLY explains what is 'appropriate or not' and the example homework from our online book, they answers were always it wasn't appropriate.
Activity A2-4 is on page 78 of your textbook. It asks you to go to finance.yahoo.com and enter the ticker symbol for Apple Corporation stock (AAPL). A page will open up which contains information on Apple, including interactive charts which allow you to see the movements in Apple's stock price over a selected period of time. Also included are Apple's most recent financial statements. Find the most recent financial statement information (not the 2008 information that is contained in the solution posted on the Blackboard site). Activity A2-4 then asks 10 questions about information that is contained in the financial statements. For example, question #7 asks what the annual dividend is on Apple stock. Take turns finding the answers to these questions until all 10 questions have been answered. Then think about whether you would invest money in Apple stock right now. Do you think it is over or under-priced? Why?
