Question

Suppose the lengths of human pregnancies are normally distributed with u = 266 days and o = 16 days.

Suppose the lengths of human pregnancies are normally distributed with µ= 266 days and o = 16 days. Complete parts (a) and (b) below.
(a) The figure to the right represents the normal curve with u= 266 days and o = 16 days. The area to the right of X= 295 is 0.0350. Provide two
interpretations of this area.
Provide one interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice.
(Type integers or decimals.)
O A. The proportion of human pregnancies that last less than
days is
O B. The proportion of human pregnancies that last more than
266
295
days is
Provide a second interpretation of the area using the given values. Select the correct choice below and fill in the answer boxes to complete your choice.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
