Question

A light travels daily from Pittsburgh to San Antonio. The following list gives the flight's arrival time (in minutes) relative to the scheduled arrival time for a
selection of 9 days. (A negative number means the flight arrived that many minutes early.)

Answer 1

Answer:

Explanation:

a) We want to get the mean of the data set

To get this, we have to divide the sum of the numbers by their count

Mathematically, we have that as:

$\frac{5+10+29+34-7+8+33+24+25}{9}\text{= }\frac{161}{9}=\text{ 17.9}$

b) To get the median, we have to arrange the numbers in descending or ascending order, then pick the middle value

We have the arrangement as:

-7,5,8,10,24,25,29,33,34

From what we have here, the medain value is 24

c) Zero mode

This is because, all the values one time. It it not possible to have a mode as all values have occurred once
