Lets do step by step
For part A) level of significance = 0.05
Test statistic F = 5.93
Df => 2 , 7
Critical value = 4.7374 ( Using F table)
Test statistic > critical value so the overall model would be considered statistically significant.
For part B
R^2 = 0.522562 = 0.53
So the model explains nearly 63 percent of the variation in the dependent variable.
For part C
p-value corresponding to 0.010919
So p value < 0.05 so the variable X1 has a slope coefficient that is significantly different from zero.
So all options are correct.
So correct option is
D) All of the above are true.
