a) For each sample size and sample standard deviation, calculate the estimated standard error.

i) n = 100, s = 20 ii) n = 100, s = 5 iii) n = 400, s = 20 iv) n = 36, s = 5 v) n = 1,200, s = 20

b) Discuss the patterns you see in the calculated standard errors. What does this tell you about sampling error and variability in sampling?
