Base area = 6 ( 1/2 x 6 x 5.2) = 93.6 cm²
Volume = base area x height = 93.6 x 17 = 1591.2cm ³
-------------------------------------------
Answer: Volume = 1591.2 cm³
-------------------------------------------
Margin of error, e = Z*SD/Sqrt (N), where N = Sample population
Assuming a 95% confidence interval and substituting all the values;
At 95% confidence, Z = 1.96
Therefore,
0.23 = 1.96*1.9/Sqrt (N)
Sqrt (N) = 1.96*1.9/0.23
N = (1.96*1.9/0.23)^2 = 262.16 ≈ 263
Minimum sample size required is 263 students.
