Explanation / Answer

9) Answer A

While looking in to the plot, seems Residuals were Normally distributed in between -4 to 4 of Y axis.

Error value will be considered as Zero or as Mean on linear regression

Variance in between observations is varied.

Even though values seems independent but normally distributed.

10 ) Answer C:

As per Standardised residuals confidence interval should be 95%. So, which means should fall in between -2 to 2

-3 to 3 covers 99.7% area

-1 to 1 covers 68.27% area

-2 to 2 covers 95.47% area

-1 to 0 covers 34.13% area

11) Answer is B

As per standardized residuals plot observations should fall in range between -2 to 2

From above plot, seems one observation is above +2 and one is below +2. so, answer will be 2.
