Accepted Solution
A:
Answer:5.514Step-by-step explanation:we have given [tex]\bar{p}[/tex]=62% =0.62n=528claim : most of adults erase all their personal information online ([tex]p> 0.5[/tex]p=0.5 q=1-p=1-0.5=0.5now test statistic is [tex]\frac{\bar{p}-p}{\sqrt{\frac{pq}{n}}}=\frac{0.62-0.5}{\sqrt{\frac{0.5\times 0.5}{528}}}=5.514[/tex]so the test statistic =5.514
