Transcribed Image Text:Part 1: Do an estimate of a linear regression model relating grades of students to their
gender (Take note: 1 - male, o - female).
a. Interpret the value of the slope coefficients for gender.
b. Is it statistically significant at the 99% level of significance?
Part 2: Do an estimate of a linear regression model relating current grade weighted
average of students to their gender, available internet speed (mbps) and previous grade
weighted average (Take note: 1 - male, o - female).
c. Interpret the slope coefficients (discuss their values and statistical significance)
d. Are the coefficients jointly statistically significant? Explain your answer.
e. How much of the variability of the current grade weighted average is explained by the
variability of the model?
