Assume that the duration of human pregnancies can be described by a Normal model with mean 206 days and standard deviation 14 days a) What percentage of pregnancies should last between 271 and 278 days? b) At least how many days should the longest 10% of all pregnancies last? Suppose a certain obstetrician is currently providing prenatal care to 74 pregnant women Let y represent the mean length of their pregnancies According to the Central Lime Theorem, what's the distribution of this sample mean, y? Specify the model, mean, and standard deviation d) What's the probability that the mean duration of these patients' pregnancies will be less than 255 days? a) The percentage of pregnancies that should last between 271 and 278 days is (Round to two decimal places as needed) b) The longest 10% of all pregnancies should last at least days Round to one decimal place as needed.)
