Selling price and amount spent advertising were entered into a multiple regression to determine what affects flat panel lcd tv sales. according to the output below, the calculated t-statistic to determine if amount spent on advertising is a significant independent variable in explaining sony bravia sales is dependent variable is sales predictor coef se coef t p constant 90.19 25.08 3.60 0.001 price -0.03055 0.01005 -3.04 0.005 advertising 3.0926 0.3680 8.40 0.000 select one:

Answer = 54

Explanation:

       Predictor                  Coef              SECoef               T             P

       Constant                  90.19             25.08              3.60         0.001

         Price                     0.03055       0.01005          −3.04         0.005

     Advertising              3.0926          0.3680             8.40         0.000

The required multiple regression model is :  

y = 90.19 - 0.03055   Price + 3.0926 Advertising

The estimated value of y for Price = 2199 and Advertising = 10 is :

y = 90.19-0.03055 x 2199+3.0926 x 10 = 53.94 ≈ 54

So , the number of units sold on average at a store that sells the Sony Bravia for $2199 and spends 10% of its advertising budget on the product is ≈ 54

metallurgy is your answer

the "study of metals and the process of refining ("

note that it says metal. metallurgy has the word "metal" in it, and so is most likely your answer (and is your answer).

rational decision making is a multi-step process for making choices between alternatives. the process of rational decision making favors logic, objectivity, and analysis over subjectivity and insight. the word “rational” in this context does not mean sane or clear-headed as it does in the colloquial sense.
