Answer:
Sample mean =119.42
Median = 92
25% trimmed mean = 102.42
10% trimmed mean = 95.69
Step-by-step explanation:
Data in increasing order :
12 13 20 23 31 35 40 43 48 49 58 62 66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141 147 159 161 168 183 207 249 262 289 323 388 513
Total no. of observations = 50
Sample mean =  
 
=  = 119.42
 = 119.42
Median: Since we have even number of observation 
Median =  =
 =  = 92
 = 92
10% Trimmed Mean: We remove 5 values from each side
Trimmed set = 35 40 43 48 49 58 62 66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141 147 159 161 168 183 207 249 
Trimmed mean =   =
 =  = 102.42
 = 102.42
25% Trimmed Mean: We remove 12 values from each side.
Trimmed set =  66 67 69 71 73 77 78 79 82 85 86 89 91 93 97 99 101 105 106 106 112 117 124 135 139 141 
Trimmed mean =   =
 =  = 95.69
 = 95.69
 
        
             
        
        
        
With two employee shifts, each will work 12 hours  (2 x 12)
With three employee shifts, each will work 8 hours (3 x 8)
With four employee shifts, each will work 6 hours   (4 x 6)
With six employee shifts, each will work 4 hours   ( 6 x 4)
With twelve employees shifts, each will work 2 hours   ( 12 x 2)
        
                    
             
        
        
        
Answer: The value of x = 1.
