Determine the null and alternative hypotheses for this test. Choose the correct answer below.
A. Ho: P1 =P2 = P3 = P4 = 0.25
Ha: At least one of the multinomial probabilities does not equal its hypothesized value.
O B. Ho: P, # P2 #P3 #P4
Ha: At least one of the multinomial probabilities equals its hypothesized value.
O C. Ho: P1 =P2 = P3 = P4 = 0.25
Ha: P1 # P2 # P3 # P4
Now find the test statistic.
