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 = 0.05 level of significance. Category 1 Category 2 Category 3 Failures 54 57 45 Successes 77 36 66 State the hypotheses. Choose the correct answer below. A. Ho: P1 = P2 = P3 H,: At least one of the proportions is different from the others. O B. Ho: The categories of the variable and success and failure are independent. H: The categories of the variable and success and failure are dependent. C. Ho: The categories of the variable and success and failure are dependent. H4: The categories of the variable and success and failure are independent. O D. Ho: H1 =E1 H2 = E2 and µ3 = E3 H1: At least one mean is different from what is expected. and %3D What is the P-value?
