Previous studies indicate no difference in the ages of the two audiences (The mean age of each audience is the same.) Lucy plans to test this hypothesis using a random sample of 100 from each audience. Her null hypothesis is Omlmzs 1 lem2= 0 (Fm-"12: 0 Omlmz :e o 'Tml -m22 0 1 7 Consider the following null and alternative hypotheses.
