A test of H0: p = 0.4 versus Ha: p > 0.4 has the test statistic z = 2.52. Part A: What conclusion can you draw at the 5% significance level? At the 1% significance level? (6 points) Part B: If the alternative hypothesis is Ha: p ≠ 0.4, what conclusion can you draw at the 5% significance level? At the 1% significance level? (4 points)

Answer

Significance tests  test of  versus  has test statistic  . (a) What conclusion would you draw at the 5 significance level? At the 1 level? (b) If the alternative hypothesis were  what conclusion would you draw at the 5 significance level? At the 1 level?
