Question

The adult eastern hellbender (a type of giant salamander) has a length which is normally distributed with a mean of 30.3 cm and a standard deviation of 3 cm, while the adult Ozark hellbender has a length which is normally distributed with a mean of 33.4 and a standard deviation of 5.

Random samples of a size 100 are selected of each species of hellbender. The box plots are created for each dataset. Which box plot will most likely have the larger interquartile range ?

a. The IQR will be around the same for each. 0

b. The eastern hellbenders. 0

c. The Ozark hellbenders. 0

d. Either is equally likely to be larger than the other. 0

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.
