Answer:
11060.83
Step-by-step explanation:
Sum = 10000 + 10250 + 10790 + 9865 + 15350 + 10110
 
 = 66365
No. of days (N) = 6
Arithmetic mean = Sum/ N
 = 66365/6
 = 11060.83

Answer:
μ =2.23


Step-by-step explanation:
Radio(x)                            weeks                           P(x)
0                                         5                                 5/100 = 0.05
1                                           27                               27/100=0.27
2                                          27                                 27/100 = 0.27
3                                         27                                 27/100 = 0.27  
4                                           9                                    9/100=0.09
5                                             5                                    5/100=0.05
We know that
Mean ,μ

μ = 0 x 0.05 + 1 x 0.27 + 2 x 0.27 + 3 x 0.27 + 4 x 0 .09 + 5 x 0.05
μ =2.23





 
        
             
        
        
        
Your answer would be 60, you can multiply 15 by 4 to get that answer. If you plug in 60 for x it will work
