le of some 23 . We take a random sample of n individuals and measure the value of some variable X . We conduct a hypothesis test of Ho : M = 30 VS . Ha : 1 30 at the 5% level of significance . We calculate a sample mean ( of a = 33 and we reject the null hypothesis . Which of the following must be true ? ( 1 ) A test of Ho : M = 30 VS . Ha : 1 30 at the 10% level of significance would also result in the rejection of He ( 1 1 ) A test of Ho : M = 30 VS . Ha : > 30 at the 5% level of significance would also esult in the rejection of H ( III ) A test of Ho : 1 31 VS . Ha : 1 31 at the 5% level of significance would also result in the rejection of H .
