    Answer: 0.1548

    Step-by-step explanation:

    The P value can be calculated from the value of the test statistic :

    H0 : p ≤ 0.28

    H1 : p > 0.28

    Zstat :

    (p – p0) / √((p0(1-p0))/n)

    p = 0.32 ; p0 = 0.28 ; n = 130

    (0.32 – 0.28) / √((0.28(1 – 0.28))/130)

    Zstat = 1.0157490

    Zstat = 1.016

    Using a 0.05 significance ;

    The P value obtained using the p value from z statistic calculator is 0.154815
