The given functions are
Evaluate the functions.
1. Because 7/4 > 1 and the exponent is positive,
the function does not decay.
2.Because 4/5 < 1 and the exponent is negative,
the function does not decay.
3. Because 8/7 > 1 and the exponent is negative,
the function decays.
4. Because 9/2 > 1 and the exponent is positive,
the function does not decay.
A composite plot the functions verifies the answer.

Answer:
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:
