Length (in days) of human pregnancies is a normal random variable (X) with mean 266, standard deviation 16.

(It would be useful to sketch this normal distribution yourself, marking its mean and the values that are 1, 2, and 3 standard deviations below and above the mean. Click to compare your figure to ours)

The probability is 0.95 that a pregnancy will last between ?218234250266282298 and ?218234250266282298 days.

The shortest 16% of pregnancies last less than ?218,234,250,266,282,298 days.

The probability of a pregnancy lasting longer than 314 days is Select an answer0.00150.0250.160.680.950.997 .

There is a probability of 0.5 that a pregnancy will last longer than ?218,234,250,266,282,298 days.
