Question

The birth registry in a hospital collects information from the mother and within this it collects the mother's weight gain during pregnancy (in pounds). According to the data obtained for 2010, the mothers' weight gain during that year had a normal distribution with a mean of 30.23 pounds and a standard deviation of 13.84 pounds. If a mother is randomly selected from this population, what is the probability that during her pregnancy she gained between 10 and 20 pounds in weight?

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.
