Hypothesis Testing, P-values: For the given alternate hypothesis (H1) and test statistic (z), determine the P-value of the test statistic. Use the answer found in the z-table or round to 4 decimal places. (a) H1: p < 0.75 The test statistic is z = −2.83. P-value = (b) H1: p > 0.85 The test statistic is z = 1.84. P-value = (c) H1: p ≠ 0.15 The test statistic is z = 1.85. P-value =
