Sladkaya [172]

Answer:

The minimum sample size required is 5,499 computer users.

The major obstacle is that it is a big sample size if it is a small organization wanting to perform it.

Step-by-step explanation:

We need to calculate a sample size in order to have 95% confidence interval with 12 minutes of witdth.

So, we have that the difference between the upper limit and the lower limit is 12:

$UL-LL=12$

$(\mu+z*\sigma/\sqrt{n})-(\mu-z*\sigma/\sqrt{n})=12\\\\2z\sigma/\sqrt{n}=12\\\\\sqrt{n}=(1/6)*z\sigma\\\\n=(1/36)z^2\sigma^2$

For a 95% CI, the value of z is 1.96. The standard deviation is 227.

$n=z^2\sigma^2/36=(1.96)^2*(227)^2/36=3.8416*51,529/36=5498.72\\\\n=5499$

The minimum sample size required is 5,499 computer users.

Komok [63]

Answer:

There are 476 pedal turn in one mile.

Step-by-step explanation:

We are given the following in the question:

Ratio of pedal turns to rear-wheel turns =

$4:7$

Number of wheel turns in one mile = 833

Let x be the number of pedal turns.

Thus, we can write:

$\dfrac{4}{7}=\dfrac{x}{833}\\\\\Rightarrow x = \dfrac{833\times 4}{7}\\\\\Rightarrow x = 476$

Thus, there are 476 pedal turn in one mile.
