The length of human pregnancies from conception to birth

Reference no: EM13635727

The length of human pregnancies from conception to birth approximates a normal distribution with a mean of 266 days and a variance of 256 days. What proportion of all pregnancies will last between 240 days and 270 days (roughly between 8 and 9 months)? Draw a normal curve to illustrate your probability.
