you did not answer this Let p be the true proportion of firms with a chief marketing officer currently on their top management team. To conduct the hypothesis test, the null and alternative hypotheses are formulated as: H₀: p̄ p̄ = 0.42'; Haa: p̄ p̄ ≠ 0.42 H₀: p ≥ 0.42; Haa: p < 0.42 H₀: p = 0.42; Haa: p ≠ 0.42 H₀: p ≤ 0.42; Haa: p > 0.42 If the null hypothesis is true, the sampling distribution of the sample proportion p̄ p̄ can be approximated by a _____ with a mean ______ and a standard deviation of ____ . The test statistic is _____ .
