Answer #1

t-tests and ANOVAs involve the use of categorical predictors, while linear regression involves the use of continuous predictors. ... When comparing between 2 groups, there are 2 parameters in the regression model that need to be estimated: b0 and b1,therfore simple regression cannot be used to test the significance of the difference 3 or means ,test the significance;significance test uses data to evaluate a hypothesis by comparing sample point estimates of parameters to values predicted by the hypothesis.

A sample of 200 monthly observations is used to run a simple linear regression: Returns = β0 + β1 Leverage + ε. A 5% level of significance is used to study if leverage has a significant influence on returns. The value of the test statistic for the regression coefficient of Leverage is calculated as t198 = –1.09, with an associated p-value of 0.2770. The correct decision is to ________.
