The arithmetic mean (also called the mean) is the most commonly used measure of central tendency. It is calculated by summing up the observed numerical values of a variable in a set of data and dividing the total by the number of observations involved.
The median is the middle value in an ordered sequence of data. If there are no ties, half of the observations will be smaller than the median, and half of the observations will be larger than the median. In addition, the median is not affected by extreme values in a set of data. Thus, whenever an extreme observation is present, it may be more appropriate to use the median, rather than the mean to describe a set of data.
The sick leave of all employee in the company need not be the same number. More than seven sick leaves will be for only for few people in the company. The frequency of the people who have sick leaves number is relatively high. Thus, the data set will have right skewed distribution for the company, since the mean is high.
Whereas the median number of sick leave is used by the union, since only less number of 3 days will be given for the union.

The owner of a large equipment rental company wants to make a rather quick estimate of the average number of days a piece of ditch-digging equipment is rented out per person per time. The company has records of all rentals, but the amount of time required to conduct an audit of all accounts would be prohibitive. The owner decides to take a random sample of rental invoices. Fourteen different rentals of ditch-diggers are selected randomly from the files, yielding the following data. She wants to use these data to construct a \(99\%\) confidence interval to estimate the average number of days that a ditch-digger is rented and assumes that the number of days per rental is normally distributed in the population. Use only the appropriate formula and/or statistical table in your textbook to answer this question. Report your answer to 2 decimal places, using conventional rounding rules.
