(a) which of the following describes the meaning of the significance level ? for a test of the hypotheses: h0: mu = 2 versus ha: mu > 2 ?
a) alpha is the probability of selecting a sample whose data leads us to the decision to reject h0 when in reality mu = 2 is true.
b) alpha is the probability of selecting a sample whose data leads us to the decision fail to reject h0 when in reality mu = 6 is true.
(b) the power of the test in (a) when the true value of the population mean is mu = 6 is
a) the probability of selecting a sample whose data leads us to the decision to reject h0when mu = 6 is true.
b) the probability of selecting a sample whose data leads us to the decision to fail to reject h0 when mu = 2 is true.
