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

➷ You can use this formula:
area = 1/2ab * sinC
Substitute the values in:
area = 1/2(17)(15) * sin(35)
Solve:
area = 73.13099
This can be rounded to give the answer of:
73.1 m^2
