Please explain T statistic

The following table contains the number of successes and failures for three categories of a variable. Test whether the proportions are equal for each category at the a = 0.01 level of significance. Category 1 Category 2 Category 3 Q Failures 77 47 45 Successes 58 52 39 a Click the icon to view the Chi-Square table of critical values. State the hypotheses. Choose the correct answer below. 'VA- H05P1=Pz = Pa H1 : At least one of the proportions is different from the others. B. H0: The categories of the variable and success and failure are dependent. H1: The categories of the variable and success and failure are independent. C. H02p1=E1 and p2 =E2 and p3 =E3 H1: At least one mean is different from what is expected. D. H0: The categories of the variable and success and failure are independent. H1: The categories of the variable and success and failure are dependent. Compute the value of the chi-square test statistic. X0 (Round to three decimal places as needed.)
