Answer:

6.76

Step-by-step explanation:

Let us create hypothesies as

[tex]H_0: p =0.50\\H_a: p>0.50[/tex]

(right tailed test for claiming most adults would erase)

Sample proportion p = 0.64

n = sample size = 582

Std error of proportion= [tex]\sqrt{\frac{0.5*0.5}{582} } \\=0.0207[/tex]

P difference = 0.14

Test statistic = p difference/std error

= 6.755

=6.76
