Question

The mean mass of 500 kudu at a private game park is 151 kg and the standard deviation is 15kg. Assume that there is a normal distribution of the masses.

(a) Calculate the proportion of kudus that have an average mass between 120 and 155 kg.

(b) Calculate the percentage of kudus that have an average mass greater than 185kg.

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.
