Is the attached problem a two sample test for a two sample normal means hypothesis test? Not sure how to answer the problem. Q-1) In the paper "Persistent Pulmonary Hypertension of the Neonate and Asymmetric GrowthRestriction" (Obstetrics & Gynecology, Vol. 91, No. 3, pp. 336-341), M. Williams et al. reported on astudy of characteristics of neonates. Infants treated for pulmonary hypertension, called the PH group,were compared with those not so treated, called the control group.PHControl33.935.233.433.437.934.332.531.836.231.535.135.634.531.331.333.132.934.134.131.936.733.532.435.231.935.135.835.134.832.836.036.333.634.534.0a. At a = 0.1 level of significance, do the data provide sufficient evidence to conclude that variationin head circumferences differs among neonates treated for pulmonary hypertension and thosenot so treated?b. What assumptions about the distribution of head circumference for each group is necessary forthe test you conducted in part (a) to be valid?c. Conduct an appropriate test to compare the mean head circumference between the twogroups. Report the p-value of this test and state your conclusions.
