We are using matched-pairs, to study whether smoking women have smaller babies than non-smoking women. Each pair involves two women of the same age: one woman is a non-smoker, and the other a smoker. To calculate our test statistic, we subtract the birthweight of the smoker's baby from the birthweight of the non-smoker's baby. Using 71 pairs of women, we find d = 7.648 and S. 20.367; and the value of our test statistic is 3.1641 Answer the following questions, providing enough detail to justify your answers: (a) Find the null hypothesis and the alternative hypothesis (b) Is this a left-tailed, right-tailed or two-tailed test? (c) Find the P-value (d) Should we reject the null hypothesis at level-of significance 0.001? (e) Should we reject the null hypothesis at level-of significance 0.01?

Transcribed Image Text:We are using matched-pairs, to study whether smoking
women have smaller babies than non-smoking women.
Each pair involves two women of the same age: one woman
is a non-smoker, and the other a smoker. To calculate our
test statistic, we subtract the birthweight of the smoker's
baby from the birthweight of the non-smoker's baby.
Using 71 pairs of women, we find d = 7.648 and S =
%3D
20.367; and the value of our test statistic is 3.1641
Answer the following questions, providing enough detail to
justify your answers:
(a) Find the null hypothesis and the alternative hypothesis
(b) Is this a left-tailed, right-tailed or two-tailed test?
(c) Find the P-value
(d) Should we reject the null hypothesis at level-of
significance 0.001?
(e) Should we reject the null hypothesis at level-of
significance 0.01?
