a. A baby is at increased risk of long term health problems if it is born on or before 224 days (32 weeks) of pregnancy. Find the probability that a randomly selected pregnant female gives birth after 224 days. Show the area under the normal curve.b. What is the 99th percentile for this distribution?

The natural length of human pregnancies (that yield a live birth) varies according to a normal distribution with mean, = 266 days, and standard deviation, 0' = 16 days. Let X be the natural length of human pregnancies (that yield a live birth). Thus X ~ My = 266,02 =162)
