<h3>How to solve for the value of n</h3>The confidence level is 95%
1 - 0.95 = 0.05
We have to get the z value at 0.05
0.05/2 = 0.025
Using the standard normal table, the critical value at 0.025 = 1.96
We have to define the probability as P = 50% = 0.5
we have to define q = 1 - 50% = 0.5
The formula that would be used to find the value of n is given as
These variables used are:
pq = variance of population
E = margin of error = 0.01
critical value = Zc = 1.96
= 0.25 * 38416
= 9604
Hence the sample space is given as 9604

r=0.25 miles
l=2×
=0.5 × 3.14
=1.57
120(minutes)÷2(miles)=60(minutes per mile)
60×1.57=94.2 minutes
