One-tail t tests. A study of the demand for imported motorcycles recently appeared in an industry newsletter. According to the study, demand for motorcycle imports is described by the function: Standard error of the estimate = 30 Here Q<sub>Y</sub> is the quantity of motorcycles imported (000), P<sub>Y</sub> is average motorcycle price ($), P<sub>X</sub> is the average price of imported compact cars, A<sub>Y</sub> is motorcycle industry advertising ($000,000), A<sub>X</sub> is industry advertising of compact cars ($000,000), and I is average disposable family income ($000). The standard errors of the exponents in the multiplicative demand function above are: And finally, this demand function was estimated using two years of monthly data (24 observations). Standard error of the estimate = 30
