Answer:

The null hypothesis is H0; u1 - u2 = 0

The mean age of each audience is the same.

Step-by-step explanation:

The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.

Therefore, for the case above;

Let u1 represent the mean age of audience for American idol and

u2 represent the mean age of audience for 60 minutes.

The null hypothesis is H0; u1 - u2 = 0

The mean age of each audience is the same.
