First to find the median we need to put the numbers in order from least to greatest.
62, 64, 65, 66, 67, 69, 83
Now take a number from each side
64, 65, 66, 67, 69
Once again.
65, 66, 67
On last time
66
So the median is 66.
Now to find the mean we must add all the numbers up
64+67+83+65+66+62+69
which equals 476
Now divide 476 by the total number of heights which is 7
476/7=68
So the mean is 68
Answers: Mean; 68 Median; 66
 
        
                    
             
        
        
        
Answer:
a) P) 0.25 = 1/4  both
b) P) 0.75 = 3/4  one
c) P) 0.25  = 1/4  none
Step-by-step explanation:
4 routes to D + H
6 routes to H + S
= D  H   S
      4  | 6
     - 2 | -3
=    2  |  3  = route 1 = 2/4  and route 2 = 3/6
= 1/2 route 1 and 1/2 route 2
Answer a ) = 1/2 x 1/2 = 0.25 = 1/4  = 0.25 probability
Answer b)  = 1- (1/2 x 1/2) = 1- 0.25 = 3/4 = 0.75 probability
Answer c)  = 1/2 x 1/2 = 0.25 = 1/4 = 0.25 probability
