    Answer:

    6.76

    Step-by-step explanation:

    Let us create hypothesies as

    H_0: p =0.50\\H_a: p>0.50

    (right tailed test for claiming most adults would erase)

    Sample proportion p = 0.64

    n = sample size = 582

    Std error of proportion= \sqrt{\frac{0.5*0.5}{582} } \\=0.0207

    P difference = 0.14

    Test statistic = p difference/std error

    = 6.755

    =6.76
