Inverse Normal Distribution

The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of tw…

Mean, Median, Mode

It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency o…

Z-Scores

A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow compar…

Textbook Question

Chapter 6.A, Problem 42E

Airline Delays. Suppose you are a scheduler for a major airline, analyzing a distribution of flight delays (departures) during one day at an airport. The distribution of delay times has the following properties: The mean delay is 10 minutes, the median delay is 6 minutes, the mode of the distribution is 0 minutes, and the maximum delay is 25 minutes.

a. Draw a rough sketch of the distribution with clearly labeled axes. Is the distribution skewed (and if so, which way) or symmetric?

b. What percentage of flights were delayed less than 6 minutes?

c. What percentage of flights were delayed more than 6 minutes?

d. Discuss the pros and cons of using the mean and the median to present the average flight delay of your airline to the public.
