Answer:
68 %
Step-by-step explanation:
(a) Using the 68-95-99.7% rule, between what two lengths do the most typical 68% of all pregnancies fall?
95%? 99.7%?
The middle 68% of all pregnancies last between 266-16 and 266+16 days, 250 to 282. The middle 95% of all
pregnancies last between 266-2*16 and 266+2*16 days, 234 to 298 (for future reference, note that this “rule” is
rounded somewhat compared to the charts). The middle 99.7% of all pregnancies last between 266-3*16 and
266+3*16 days, 218 to 314.
