Hi there I am having a hard time with this question. Exercise 10.6. Nurses who are interested in the effect of antenatal care divided a group of 18 pregnant women into two groups of size 9. Group 1 received antenatal consultations, while women in group 2 did not receive consultations. prenatal. Descriptive statistics on birth weight are x1 = 99.6 ounces and s1 = 6.82 ounces for group 1, respectively x2 = 85.3 ounces and s2 = 16.75 ounces for group 2. Give an interval 95% confidence for i - 2, where i is the mean birth weight for babies of women who have received antenatal care, and 2 is the mean birth weight for babies of women who have not. received prenatal consultations. Using this interval, can we conclude that women who have not received antenatal care have babies with a lower weight? Suppose the two populations follow normal laws of unequal variances
