Answer:
Follows are the solution to this questrion: 
Step-by-step explanation:
In point a:
Nominal -scale  
Qualitative -Variable  
In point b:
Table of frequency  
Frequency of results  
early =22  
On time =68  
 Late =7
Lost= 1
In point c:
Relative list of frequencies (about two decimal places)  
Frequency of results  
 Early =0.23    
On time =0.69  
 Late = 0.07  
 Lost  = 0.01 
In point d:
Early or early packing packets =92%  
 packages missing= 1%
 
        
             
        
        
        
I put in the x coordinate for where y was 80 and the y coordinate for where x was 3. Then I subtracted them to get the slope. Hope this helps.
 
        
        
        
X=1 and y=4. first I did 
3x+2y=11
y=5x-1
and 3x+2(5x-1)=11
=3x+10x-2=11
=13x-2=11
cancel 2 out
13x=13
x=1. then simply add x in the original y equation,
y=5x-1
y=5(1)-1
y=5-1
y=4.
check your work
3(1)+2(4)=11
4=5(1)-1 
again X=1 AND Y=4 
Hope this helped
