Maria records random speeds from three different Internet providers in the table. Provider Download Speed (megabits per second)
Igoryamba

Answer:

<em>Able Cable </em>

Step-by-step explanation:

<u>Mean Value of Samples</u>

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:

\displaystyle \bar x=\frac{\sum x_i}{n}

We need to evaluate the mean value of the three internet providers mentioned in the question.

For CityNet:

\displaystyle \bar x_1=\frac{3.6+3.7+3.7+3.6+3.9}{5}=3.7

For Able Cable:

\displaystyle \bar x_2=\frac{3.9+3.9+4.1+4.0+4.1}{5}=4.0

And for Tel-N-Net:

\displaystyle \bar x_3=\frac{3.9+3.7+4.0+3.6+3.8}{5}=3.8

We can conclude Able Cable offers the fastest mean downloading internet speed

A lightbulb has a normally distributed light output with mean 5000 end foot-candles and standard deviation of 50 end foot-candle
Blizzard [7]
To find the specification limit such that only 0.5% of the bulbs will not exceed this limit we proceed as follows;
From the z-table, a z-score of -2.57 cuts off 0.005 in the left tail; given the formula for z-score
(x-μ)/σ
we shall have:
(x-5000)/50=-2.57
solving for x we get:
x-5000=-128.5
x=-128.5+5000
x=4871.50
