Question

A jar full of marbles is displayed the following table shows the guesses for 10 people. The actual number of marbles in the jar is 145. Calculate the absolute guessing error for all 10 guesses.

Answer 1

Explanation:

To calculate the absolute guessing error, we need to find the absolute difference between each guess and the actual number of marbles (145).

Guess Absolute Guessing Error

190 45

150 5

125 20

133 12

167 22

160 15

148 3

200 55

170 25

115 30

To check, we can verify that each absolute guessing error is the positive difference between the guess and 145.
