Answer:

5.514

Explanation:

we have given
\bar{p}=62% =0.62

n=528

claim : most of adults erase all their personal information online (
p> 0.5

p=0.5 q=1-p=1-0.5=0.5

now test statistic is


\frac{\bar{p}-p}{\sqrt{(pq)/(n)}}=\frac{0.62-0.5}{\sqrt{(0.5* 0.5)/(528)}}=5.514

so the test statistic =5.514
