Determine the absolute error and the relative error.

Please show your work so I can understand, thanks!

  (B)  Absolute, 11; Relative, 3.8%

Step-by-step explanation:

Before you can compute any errors, you need to know the value against which error is being measured. Here, it seems to be the number of people the poll indicates are ready to buy: 127 +162 = 289. The estimated value of 300 is being compared against this "actual" or "accurate" value of 289.

Absolute Error

The absolute error is the difference between the estimate and the actual value:

  300 -(127 +162) = 300 -289 = 11 . . . . absolute error

__

Relative Error

The relative error is the absolute error expressed as a fraction of the actual value. Often, that fraction is given as a percentage.

  11/289 ≈ 0.038062 ≈ 3.8% . . . . relative error

49%

when you realize that you dont know just realize i just took a test and im so smart
