A software firm survey of 563 randomly selected adults showed that 60% of them would erase all of their personal information online if they could. Express the original claim in symbolic form. Let the parameter represent the adults that would erase their personal information. Find the value of the test statistic.

a)Claims: P>0.5("MOST" of the adult erase their personal information)

p=0.5

q=1-p=1-0.5=0.5
