Q:
Find the minimum sample size required to estimate a population mean μ of daily
randfall. We want 99% confidence that the sample mean is within .010 inches of
the population mean, and the population standard deviation is known to be .212 inches.
A:
z%5B0.005%5D+ = 2.5758
n = %28%282.5758%2A.212%29%2F.010%29%5E2 ≈ 2982
Therefore, the required sample size is at least highlight%282982%29
