• Q2
What is the purpose of hypothesis testing in regression analysis?
To estimate the regression coefficients.

• Q3
What is the difference between simple linear regression and multiple linear regression?
Simple linear regression is used for time series analysis, while multiple linear regression is used for cross-sectional data.
Simple linear regression is used for categorical variables, while multiple linear regression is used for continuous variables.
Simple linear regression does not assume a linear relationship, while multiple linear regression assumes a linear relationship.
Simple linear regression involves one independent variable and one dependent variable, while multiple linear regression involves one dependent variable and two or more independent variables.
Simple linear regression does not require any assumptions, while multiple linear regression requires multiple assumptions.

• Q7
In regression analysis, what does the p-value measure?
The probability of obtaining the observed data or more extreme values, assuming the null hypothesis is true.
The average value of the dependent variable.
The explained variation in the dependent variable.
The correlation coefficient between the independent variable(s).
