    Answer:

    p(s)  = – 2.71

    Step-by-step explanation:

    Test of proportion

    sample size       n  =  350

    Publisher report             37 %      0,37

    Sample proportion          30 %      0.30

    p(s)  = [ ( p  –  p₀ ) /√(p₀q₀/n ]      ⇒  p(s)  = – 0.07*(18.70)/√(0.37)*(0.63)

    p(s)  = – 1.3095/0.4828

    p(s)  = – 2.71
