Which statement is true about the residual plot below ?

The option should be B, after we eliminated these other 3 options with reasons as below:

A - Without details data, if we see from the plot only, there is no way to confirm the residual is greater - equal - smaller than 0

C - There is always a good regression model for any data

D - This is Heteroscedasticity case. Hence, the linear model is not a good approach.

Hope this helps!

$3720

step-by-step explanation:

taxable income = $31000

as per the 2018-2019 us tax bracket, the tax rate is 12% for an individual whose taxable income is between $9,526 to $38,700.

so, the tax to be paid by him = 12% of 31000

= 0.12 * 31000     [12% converted to decimal as 0.12]

= $3720
