Since we are not given any information about the proportion, we will assume the sample proportion to be 0.50
so,
p = 0.50
The Error is 10% percentage point. This means that on either side of the population proportion the error is 5% so E = 0.05
z = 1.645 (Z value for 90% confidence interval)
The margin of error for population proportion is calculated as:
This means 271 students should be included in the sample
374 = 33
272 = x
374/33 = 272/x
x=(33*272)/374=24 minutes
Positive 14/472 (because of rise over run when finding slope)
