Each of the digits in a raffle is thought to have the same chance of occurrence. The table shows the frequency of each digit for consecutive drawings in a California lottery. Perform the chi-square test to see if you reject the hypothesis at the 0.02 significance level that the digits are from a uniform population.
Digit | Frequency | Digit | Frequency |
0 | 41 | 5 | 35 |
1 | 40 | 6 | 37 |
2 | 41 | 7 | 32 |
3 | 31 | 8 | 33 |
4 | 38 | 9 | 32 |
a. State the decision rule. Use 0.02 significance level. (Round your answer to 3 decimal places.) H0: The digits are uniformly distributed. H1: The digits are not uniformly distributed.
Reject H0 if chi-square > ___ .
b. Compute the value of chi-square. (Round your answer to 3 decimal places.) Chi-square ___ .
