Probability
The gestation period of humans follows a normal distribution with a mean of 266 days and a standard deviation of 16 days. Find the probability that a random sample of 36 pregnancies has a mean gestation period within 5 days of the mean. O P(-1.88 < Z < 1.88) = 0.9699 – 0.0301 O P(-1.88 < Z < 1.88) = 0.0301 + 0.0301 O P(-1.88 < Z < 1.88) = 0.0301 – 0.9699 O P(-1.88 < Z < 1.88) = 1 –- 0.9699
