Answer:
20m
Step-by-step explanation:
A=s^2
root 25=s
s=5m
so to find perimeter we will use the formula 4s
P=4×5
P=20m

Answer:
And replacing the info from the problem we have:
So then the best estimator for the true proportion p is given by or equivalent to 3.2 %
Step-by-step explanation:
We want to find a confidence interval for a proportion p who represent the parameter of interest.
The confidence interval would be given by this formula:
For this case the 90% confidence interval is given by (1.8%=0.018, 4.6%=0.046) after apply the last formula
Since the confidence interval is symmetrical we can estimate the point estimator of the true percentage with this formula:
And replacing the info from the problem we have:
So then the best estimator for the true proportion p is given by or equivalent to 3.2 %
