As introduced in the book, linear regression could be useful for which of the following scenarios?

a-Each observation in the data consists of a single, qualitative variable.

b-Each observation in the data consists of two values, one for each of two nominal variables.

c-Each observation in the data comes with two values, one for each of two quantitative variables.

d-Each observation in the data consists of a single, quantitative variable.

Expert Solution

option A is incorrect because we know that the linear regression is used only for the quantitative data, but not for the qualititaive data, so it is incorrect option.

option B is incorrect because we know that the linear regression is not used for the nominal data values, it can be used only for numerical values.

option C is the correct because each observation in the data with two values, one for each of two quantitative variables, i.e. one value for the dependent variable and other for the independent variable.

so, option C is correct answer

option D is incorrect because each observation in the data consists of two values, but not a single value.

5. Under the Classical Linear Regression model assumptions, which one of the following is not a required assumption about the error term ui? * a. There is no multicollinearity in the model b.

With regard to regression models, which of the following statements is correct? i) Linear restrictions on regression parameters cannot be tested using an F-test. ii) The general-to-specific approach (also called “top-down”) starts with a model containing all explanatory variables. Subsequently, the least significant variables are dropped one by one until all of the variables remaining in the model are statistically significant. iii) Multicollinearity in a regression results in high t-statistics for individualexplanatory variables and a failure of the F-test to...
