Answer:
Able Cable
Step-by-step explanation:
Mean Value of Samples
It's central tendency statistics measure that gives one representative value out of a complete dataset. It can be computed as the sum of the values by the number of values:
[tex]\displaystyle \bar x=\frac{\sum x_i}{n}[/tex]
We need to evaluate the mean value of the three internet providers mentioned in the question.
For CityNet:
[tex]\displaystyle \bar x_1=\frac{3.6+3.7+3.7+3.6+3.9}{5}=3.7[/tex]
For Able Cable:
[tex]\displaystyle \bar x_2=\frac{3.9+3.9+4.1+4.0+4.1}{5}=4.0[/tex]
And for Tel-N-Net:
[tex]\displaystyle \bar x_3=\frac{3.9+3.7+4.0+3.6+3.8}{5}=3.8[/tex]
We can conclude Able Cable offers the fastest mean downloading internet speed
