A news reporter declares that in Seattle it rains 80% of the time, hails 15% of the time, and is sunny 5% of the time. Calculate the test statistic, degrees of freedom and the P-value. Here is a chi-square distribution table. Test statistic: X A sample of 150 randomly selected moments reveals 135 instances when it was raining, 2 instances when it was hailing, and 13 instances when it was sunny. df = P-value: Less than Do these data provide convincing evidence that this stated distribution is incorrect? Use a = 0.01.
