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 0.01 significance level that the digits are from a uniform population.

Digit Frequency Digit Frequency
0 28 5 30
1 30 6 28
2 29 7 25
3 24 8 27
4 32 9 37

State the decision rule. Use 0.01 significance level. (Round your answer to 3 decimal places.)

H0: The digits are uniformly distributed.

H1: The digits are not uniformly distributed.

Compute the value of chi-square. (Round your answer to 3 decimal places.)

What is your decision regarding H0?
