Select the correct "state” portion of the hypothesis test.
Answer
A
H0: μwithout OJ = μwith OJ H0: μwithout OJ > μwith OJ where μwithout OJ = the true mean heart rate without drinking OJ and μwith OJ = the true mean heart rate after drinking OJ.
B
H0: μwithout OJ = μwith OJ Ha: μwithout OJ < μwith OJ where μwithout OJ = the true mean heart rate without drinking OJ and μwith OJ = the true mean heart rate after drinking OJ.
C
H0: μdiff = 0 Ha: μdiff < 0 Where μdiff = the true mean difference (withoutOJ − with OJ) in heart rates for students like these.
D
H0: μdiff = 0 Ha: μdiff > 0 Where μdiff = the true mean difference (withoutOJ − with OJ) in heart rates for students like these.
