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 15 pregnancies has a mean gestation period of 260 days or less. O P(Z > -1.45) = 0.9265 O P (Z > 1.45) = 0.0735 O P (Z< -1.45) = 0.0735 O P(Z <1.45) = 0.9265
