Question

​Claim: Most adults would erase all of their personal information online if they could. A software firm survey of 528 randomly selected adults showed that 62​% of them would erase all of their personal information online if they could. Find the value of the test statistic.

Answer 1

Answer:

5.514

Step-by-step 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

$\frac{\bar{p}-p}{\sqrt{\frac{pq}{n}}}=\frac{0.62-0.5}{\sqrt{\frac{0.5\times 0.5}{528}}}=5.514$

so the test  statistic =5.514
