Question

Suppose the lengths of human pregnancies are normally distributed with = 266 days and -16 days. Complete parts a and b) below. a) The figure to the right represents the normal curve with = 266 days and -16 days. The area to the left of X-230 IS 0.0122. Provide two interpretations of this area. Provide one interpretation of the area. Select the correct choice below and fill in the answer boxes to complete your choice. Type integers or decimals. Do not round.) O A. The proportion of human pregnancies that last less than days is OB. The proportion of human pregnancies that last more than days is Provide a second interpretation of the area. Select the correct choice below and fill n the answer boxes to complete your choice (Type integers or decimals. Do not round.) A. The probability that a randomly selected human pregnancy lasts more than days is O B. The probability that a randomly selected human pregnancy lasts less than days is (b) The figure to the right represents the normal curve with = 266 days and = 16 days. The area between x = 280 and x = 305 is 0.1834. Provide two interpretations of this area. Provide one interpretation of the area.

Explanation / Answer

As per the Chegg policy, we are advised to do only one question at a time so i am attempting the 1st image.

Image - 1:

a) First interpretation: Option B; 230; 0.0122

Second interpretation: Option B; 230; 0.0122

b) First interpretation: Option B; 280; 305; 0.1834

Second interpretation: Option B; 280; 305; 0.1834
