Answer: 66 water bottles in 3 minutes.
Step-by-step explanation:
First, you see how many times 25 goes into 550.
- Your answer should be 22.(<em>22 is the amount of bottles in a minute</em>)
Next, you multiply 22 by 3 because you want to see how many bottles are produced in 3 minutes.
- Your answer should be 66.(<em>66 is the amount of bottles in 3 minutes</em>).
--- Your final answer is 66 water bottles in 3 minutes.

<em>Answer:</em>
<em>n = 1067</em>
<em>Step-by-step explanation:</em>
<em />
<em>Since nothing is known, we would assume that 50% of the computers use the new operating system.
</em>
<em>So, standard error = 0.5/SQRT(n)
</em>
<em>Z-value for a 95% CI = 1.9596
</em>
<em>So, margin of error = 1.9596 x 0.5 / SQRT(n) = 0.03
</em>
<em>So, n = 1067 (approx.)</em>
<em />
<em>This will be your approximate answer : n = 1067</em>
