The answer is the first one: The placenta sits low in the uterus, next to or covering the cervix, and vaginal delivery increases the risk of severe hemorrhaging (bleeding).

Explanation for each option:

  1. The placenta sits low in the uterus, next to or covering the cervix, and vaginal delivery increases the risk of severe hemorrhaging (bleeding): This is the correct reason why a woman with placenta previa should avoid vaginal delivery. Placenta previa occurs when the placenta partially or completely covers the cervix, which can lead to severe bleeding during labor and delivery if a vaginal birth is attempted.

  2. The placenta is underdeveloped (too small) and vaginal delivery may deprive the growing fetus of oxygen: This is not typically associated with placenta previa. An underdeveloped placenta might be a concern for fetal growth restriction, but it is not a reason to avoid vaginal delivery specifically due to placenta previa.

  3. The placenta is abnormally attached to the uterine wall and vaginal delivery increases the risk of the placenta prematurely separating from the uterus: This describes a condition known as placenta accreta, not placenta previa. Placenta accreta involves abnormal attachment, but the primary concern with placenta previa is the location of the placenta over the cervix.

  4. The placenta has a number of vascular abnormalities and vaginal delivery puts the fetus at risk for oxygen deprivation: While vascular abnormalities can be a concern, they are not the primary reason to avoid vaginal delivery in the case of placenta previa. The main issue with placenta previa is the risk of maternal hemorrhage due to the placenta's position over the cervix.

In summary, the primary reason to avoid vaginal delivery with placenta previa is the risk of severe bleeding due to the placenta covering or being near the cervix.

Use the answer key to determine that you accurately determined and interpreted errors in hypothesis testing. - If necessary, revise your work. 1. Census data reveal that the ownership rate in one small city is around 59%. The city council is debating a plan to offer tax breaks to first-time home buyers in order to encourage people to become homeowners. They decide to adopt the plan on a 2-year trial basis and use the data they collect to make a decision about continuing the tax breaks. Since this plan costs the city tax revenues, they will continue to use it only if there is strong evidence that the rate of home ownership is increasing. a. What are the hypotheses? b. What would a type I error be in this test? c. What would a type II error be in this test?
