Suppose a simple random sample of size n is taken from a population, and the variable of interest follows a normal distribution with mean μand with standard deviation σ. Use the Substitution Rule (5.4.5) to show that the probability that the sample mean lies within z units of the true population mean is independent of μand is given by (1)/(√(π)) ∫-z √(π) /(σ√(2))^z √(π) /(σ√(2)) e^-u^2 d u | Numerade
