Q:Question:
Calculate the margin of error E = zalpha/2 . Sigma/n if the necessary requirements are satisfied. The confidence level is 90%, the sample size is n = 98, and sigma = 11. Are the necessary requirements satisfied? Use the given margin of error , confidence level and population standard deviation, sigma, to find the minimum sample size required to estimate an unknown population mean, mu. Margin of error : 0.8 inches, confidence level: 95%, sigma
A:Answer:
E = 1.645*11/sqrt(98) = 1.828 n = (Z * sigma / E...
