Reference no: EM131870303

A random sample of size n = 25 obtained from a normally distributed population with unknown mean µ yielded = 26.7 and standard deviation s = 6. Prior to obtaining the sample, the mean was conjectured to be at least 28. Perform a test of hypothesis to test the conjecture at the α = .05 level of significance.
