Suppose that you have a die that may or may not be fair. On a rainy day, you toss the die 1500 times and record the outcome of each toss. After many hours and a tired arm, you found that you had rolled 282 fours. Using the following steps, conduct a hypothesis test to determine the strength of the evidence that the die is not fair.

Ho: p=1/6

Ha: p not equal to 1/6

What is the z-statistic for this test?
