Select the correct "state” portion of the hypothesis test.
Answer
A
H0: μfirst = μsecond Ha: μfirst > μsecond where μfirst = the true mean mean IQ for the firstborn twin and μsecond = the true mean IQ for the second-born twin.
B
H0: μdiff = 0 Ha: μdiff > 0 Where μdiff = the true mean difference (firstborn score − second-born score) in IQ scores.
C
H0: μdiff = 0 Ha: μdiff ≠ 0 Where μdiff = the true mean difference (firstborn score − second-born score) in IQ scores.
D
H0: μfirst = μsecond Ha: μfirst ≠ μsecond where μfirst = the true mean IQ for the firstborn twin and μsecond = the true mean IQ for the second-born twin
