Answer:

This data is not sufficient evidence to say that less than 30% of the buyer favor longer hours.

Explanation:

The given information is:

$\alpha$ = 0.05

n = 450

c = $\frac{ 125}{450}$ = 0.27778

The variable we are concerned with is X = c of buyer who favor long hours.

The proportion of buyer who prefer longer hours is then $p = \frac{X}{n}$ .
