pregnant women with gestational diabetes mellitus (gdm) are at risk for long-term weight gain and subsequent development of type ii diabetes. a pilot weight loss clinical trial was conducted where women with gdm were randomized to either an active intervention using a web-based delivery or a control intervention. women were randomized at 6 weeks postpartum and then were seen at follow-up visits at 6 months and 12 months postpartum. at 12 months postpartum, women in the active group lost a mean of 0.18 lb with a standard deviation of 15.5 lbs. hint: for all parts of this problem, assume that weights can be measured exactly and no continuity correction is necessary. a button hyperlink to the salt program that reads: use salt. (a) if we assume that the change in weight from pre-pregnancy to 12 months is normally distributed, then what percent of women in the active group were at or below their pre-pregnancy weight at 12 months postpartum? (round your answer to two decimal places.) 22.36 incorrect: your answer is incorrect. % (b) at 12 months postpartum, women in the control group gained a mean of 7.8 lbs. with a standard deviation of 15.4 lbs. compared with their pre-pregnancy weight. what is the probability that a control group woman was at or below her pre-pregnancy weight at 12 months? (hint: make the same assumptions as in part (a). round your answer to four decimal places.)
