Null and Alternative Hypotheses · Exercise 12

A recent survey of 273 randomly selected teens living in Massachusetts asked about social media. Sixty-three said that they routinely use a certain app to share pictures. The researchers want to determine if there is good evidence that more than 30 percent of teens use this app. The alternative hypothesis is as follows:

(a) p < 0.30
(b) p ≤ 0.30
(c) p ≥ 0.30
(d) p > 0.30

Its source prints no answer for this problem, so there's nothing to check against.
