Question 1.

During pregnancy, doctors monitor a woman's urine protein for signs of liver disorder, a symptom of preeclampsia; preeclampsia is a rare complication during pregnancy. When signs of liver disorder are observed, doctors obtain platelet counts from a sample of the women's blood. Platelet count for pregnant women in Canada is Normally distributed with a mean of 255,000 (with standard deviation of 35,000). When a pregnant woman's platelet count drops to the 10th percentile or lower for pregnant women in Canada, doctors become concerned about the woman's health and recommend inducing delivery early.

Consider the platelet counts given below (i.e. as answer options for this question). Based on the information above, which of these platelet counts is the lowest count that would NOT cause a doctor to recommend inducing delivery early? If more than one of these counts would not cause a doctor to recommend inducing delivery early, select the smallest (i.e. lowest) of those options.

A. 220,000

185,000

165,000

D. 150,000

answer is A.. please explain. I keep getting the answer D.
