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_Y is the quantity of motorcycles imported (000), P_Y is average motorcycle price ($), P_X is the average price of imported compact cars, A_Y is motorcycle industry advertising ($000,000), A_X 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).
