X Y 1 3 2 7 3 5 4 11     The above table gives you information regarding Y (dependent variable) and X (independent variable). The least squares estimate of b1 equals ______ and the value of residual when Xi = 3 is _______.

You have collected data for the 52 countries and estimated the following relationship between the change in the unemployment rate from the previous year ( ∆ u r ^ ) and the growth rate of the respective country real GDP (gy). The results are as follows: unemployment reg.png Assuming that the estimator has a normal distribution, the 95% confidence interval for the slope is approximately the interval:

A low regression R2 means that:

The OLS residuals:

In general, the t-statistic has the following form:

A sample of 25 observations on household expenditures for natural gas and electricity is used to estimate a linear demand function for gas.  The dependent variable (Y) is the quantity of gas consumed (thousand cubic feet), while the independent variable is electricity cost (X), measured in dollars:  Quantity of Gas Consumedi = beta0+ beta1  Electricity Costi + ui  Given β ^ 1 = 2.15 and SE( β ^ 1 ) = 0.6481,  test the hypothesis: H0: beta1 = 1 against H1: beta1  ≠ 1 at the 5% level of significance. The test statistic is [BLANK-1] (You must round your answer to three decimal places).  The critical value is [BLANK-2].  You [BLANK-3] the null hypothesis (choose reject or do not reject).
