Answer:



Step-by-step explanation:
For this case we have a confidence interval given as a percent:

If we express this in terms of fraction we have this:

We know that the confidence interval for the true proportion is given by:

And thats equivalent to:

We can estimate the estimated proportion like this:

And the margin of error can be estimaed using the fact that the confidence interval is symmetrical

And then the confidence interval in the form desired is:

well, let's say 1 meter is the 100%, now, if we know that 1 is 100%, what percentage is 70?

6375/pi mm[3] Just took the test, I hope this helps!
I think that 0.45 would be one.
