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.
