(a) Perform a hypothesis test to assess whether there are significant differences in mean BMD for the femoral neck between the heavier- and lighter-smoking twins. (Use Lighter - Heavier. Use a = 0.05.) State the null and alternative hypotheses (in g/cm2). (Enter != for # as needed.) μ₁=0 M₁!=0 Ho: H₁: X Find the test statistic. (Round your answer to two decimal places.) 0.17 X Use technology to find the p-value. (Round your answer to four decimal places.) p-value = 0.8659 State your conclusion. Reject Ho. There is sufficient evidence to conclude that there are significant differences in mean BMD for the femoral neck between the heavier- and lighter-smoking twins. H₁: Fail to reject Ho. There is insufficient evidence to conclude that there are significant differences in mean BMD for the femoral neck between the heavier- and lighter-smoking twins. Fail to reject Ho. There is sufficient evidence to conclude that there are significant differences in mean BMD for the femoral neck between the heavier- and lighter-smoking twins. Reject Ho. There is insufficient evidence to conclude that there are significant differences in mean BMD for the femoral neck between the heavier- and lighter-smoking twins. (b) Perform a hypothesis test to assess whether there are significant differences in mean BMD for the femoral shaft between the heavier- and lighter-smoking twins. (Use Lighter - Heavier. Use a = 0.05.) State the null and alternative hypotheses (in g/cm2). (Enter != for # as needed.) Ho: M₁=0 M₁!=0 X
