    B. R2
    C. F-test
    D. Durbin-Watson

    2. When the R2 of a regression equation is very high, it indicates that

    B. the intercept term has no economic meaning

    accounted for by the variation in the independent variables

    D. there is a good chance of serial correlation and so the equation must be discarded

    A 1
    B. 2
    C. -3
    D. -1

    B. indicates that a variable is expected to either have or not have an impact on a dependent variable
    C. indicates that insufficient data is available for the analysis
    D. indicates the use of hypthetical data

    5. A manager will have the least confidence in an explanatory variable that:
