Question

For a given gestation period, the birth weights can be approximated by a normal distribution. The means and standard deviations of the birth weights for various gestation periods are shown in the table below.

What percent of the babies born within each gestation period have a low birth weight (under 5.5 pounds)? (a) Under 28 weeks (b) 42 weeks and over

Describe the weights of the top 10% of the babies born within each gestation period. (a) Under 28 weeks (b) 42 weeks and over

For the gestation period of 39 weeks, what is the probability that a baby will weigh between 6 and 9 pounds at birth?

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.
