In a three-digit lottery, each of the three digits is supposed to have the same probability of occurrence (counting initial blanks as zeros, e.g., 32 is treated as 032). The table shows the frequency of occurrence of each digit for 90 consecutive daily three-digit drawings. Digit 0 1 2 3 4 5 6 7 8 9 Total Frequency 22 27 26 29 30 25 33 29 20 29 270 picture Click here for the Excel Data File (a) Calculate the chi-square test statistic, degrees of freedom, and the p-value.
