a A random sample of eight observations was taken from a normal
population. The sample mean and standard deviation are x = 75 and s
= 50. Can we infer at the 10% significance level that the
population mean is less than 100?
b Repeat part (a) assuming that you know that the population
standard deviation is σ = 50.
c Review parts (a) and (b). Explain why the test statistics
differed.
