Answer 2

Answer:

Null hypothesis H0 : u = 0.79

Alternative hypothesis Ha : u > 0.79

Where u is the proportion of their readers that owns a personal computer.

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;

Null hypothesis H0 : u = 0.79

Alternative hypothesis Ha : u > 0.79

Where u is the proportion of their reader that owns a personal computer.
