Question

the accompanying table pertains to scheduled commercial airline carriers for a certain country. complete parts (a) through (c). click the icon to view the commercial airline carrier data. (a) find the mean number of fatalities. the mean number of fatalities is 74.2. (type an integer or decimal rounded to the nearest tenth as needed) (b) find the median number of fatalities. the median number of fatalities is . (type an integer or a decimal. do not round.) commercial carrier data year departures (in millions) fatal accidents fatalities year 1 11.1 1 9 year 2 11.4 2 89 year 3 10.6 5 528 year 4 10.4 0 1 year 5 10.2 1 24 year 6 10.8 0 13 year 7 11.1 2 24 year 8 10.6 2 52 year 9 10.7 1 1 year 10 10.6 1 1

Explanation:

Step1: Arrange fatalities in ascending order

1, 1, 1, 9, 13, 24, 24, 52, 89, 528

Step2: Determine the position of the median

Since there are $n = 10$ data - points (an even number of data - points), the median is the average of the $\frac{n}{2}$th and $(\frac{n}{2}+1)$th ordered data - points. Here, $\frac{n}{2}=5$ and $\frac{n}{2}+1 = 6$.

Step3: Calculate the median

Median=$\frac{13 + 24}{2}=\frac{37}{2}=18.5$

Answer:

18.5
