Unformatted text preview: P( X > 10.5), if the population mean = 10, s.d. = 2, and a random sample of size n= 100, etc. Chapter 8: 1. Know how to find the confidence interval for population mean μ when n is large (i.e. n ≥ 30), population s.d. σ is known (hint: use zvalue) 2. Know how to find the confidence interval for population mean μ when n is large (i.e. n ≥ 30), population s.d. σ is unknown (hint: use tvalue) 3. Know how to find the confidence interval for population mean μ when n is small (i.e. n < 30), population follows a normal distribution , and σ is known (hint: use zvalue.) 4. Know how to find the confidence interval for population mean μ when n is small (i.e. n < 30), population follows a normal distribution , and σ is unknown (use tvalue) 5. If n is small (i.e. n < 30), population does not follow a normal distribution , what will you do? (hint: increase the n to be greater than 30, then decide if σ is known or not.)...
