Can you solve question A sample of MATH 117 Lab Work 1 resu

A sample of MATH 117 Lab Work 1. results in semester 352 was obtained . The data are as follows: 9.2 3.4 7.8 6.5 8.6 9.4 6.0 7.3 4.1 2.8 6.5 7.9 8.9 Find the following : mean median mode range

Solution

Ordering,

2.8
3.4
4.1
6
6.5
6.5
7.3
7.8
7.9
8.6
8.9
9.2
9.4

a)

Getting the mean, X,      
      
X = Sum(x) / n      
Sum(x) =    88.4  
As n =    13  
Thus,      

X = Mean =     6.8   [ANSWER]

***************I

b)

Here, there are 13 entries, so the 7th entry is the median:

Median = 7.3 [ANSWER]

****************

c)

The most frequent number here is 6.5,

Mode = 6.5 [ANSWER]

******************
d)

Range = max - min = 9.4 - 2.8 = 6.6 [ANSWER]
