# Question: The lengths of human pregnancies are normally distributed with

The lengths of human pregnancies are normally distributed with µ = 266 days and σ = 16 days.

(a) The ﬁgure represents the normal curve with µ = 266 days and σ = 16 days. The area to the right of x = 280 is 0.1908. Provide two interpretations of this area.

(b) The ﬁgure represents the normal curve with µ = 266 days and σ = 16 days. The area between x = 230 and x = 260 is 0.3416. Provide two interpretations of this area.
