Question

Please show me the answer of question 3 and 4

(ii) Test Ho x = μy against H₁ μx μy at significance level 0.05.
(iii) Compute the associated p-value.
(iv) Redo part (i) - (iii), but do not assume ox = σy, by pairing up the mothers of the two
groups in the order they appear.

Some nurses in county public health conducted a survey of women who had received
inadequate prenatal care. They used information from birth certificates to select mothers
for the survey. The mothers selected were divided into two groups:
Group A: mothers who said they had ≤ 5 prenatal visit.
• Group B: mothers who said they had ≥ 6 prenatal visits.
Let X be the birth weight of babies from mothers in Group A and Y the birth weight of
babies from mothers in Group B. Assume that X ~ N(μx, oz) and Y ~ N(µy, o), where
σx = σy are unknown but equal. Suppose that the result of the survey is that
Birth weight of babies from mothers in Group A:
49 108 110 82 93 114 134 114 96 52 101 114 120 116
Birth weight of babies from mothers in Group B:
