a) what percentage of Asians have weights that are within these limits

b) If the ACES-IIC expulsion seats were designed for Europeans weighing more than 167 pounds, what percentage of Asians are in this range?

c) If the ACES-II A ejection seats were designed for Europeans weighing less than 122 pounds, what percentage of Asians are in this range?

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.
