Question

11. An auditor has been assigned the task of inspecting the dice used in a local gaming resort. A fair die show's a 6 face up one-sixth of the time. In order to determine if a die for a particular game is fair, he must observe a long number of trials and record the proportion of the time that the die lands showing a 6 facing up. The graph below shows the cumulative proportion of sixes that are rolled for 100 consecutive trials of a particular game.​

Answer 1

where is the graph

Explanation:

Answer 2

e This die appears to be fair because the proportion of sixes fluctuates greatly.

Explanation:

For a fair die, we would expect the proportion of sixes to be approximately 1/6 = 0.167. Because the observed proportion is not the same as 0.167, we have reason to suspect that the die is not fair.
