Answer 1

Claim: The majority of adults would erase all of their personal information online if they could

Survey question: Would you erase all of your personal information online if you could?

Sample size: 448

Yes: 57%

No: 43%

(a)

We need to express the claim in symbolic form:

$p>0.5$

Where p is the proportion of "yes" in any survey.

(b)

The default null hypothesis is:

$\begin{gathered} H_0\colon p=0.5 \\ \end{gathered}$

For the alternative hypothesis, we use the claim:

$H_1\colon p>0.5$
