Question

A researcher measured the walking speed of travelers in the crazy town municipal airport and banana Palace regional airport. The standard deviation speed of the 35 randomly selected travelers who were departing was 46 ft./min. The standard deviation speed of the 33 travelers who were arriving was 34 ft./min. Assuming walking speed is normally distributed wet does the evidence suggest that the standard deviation walking speed is different for travelers who are departing then for travelers who are arriving?

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.
