ACTIVITY 10 - Solutions P-value Guidelines: Keep this in mind: The method for finding the p-value is based on the alternative hypothesis. Minitab will provide the p-value but if doing by hand using Table A1 observe the following: For Ha: p po then p-value = 2P(Z |z|) For Ha: p > po then p-value = P( Z z) For Ha: p < po then p-value = P( Z z) Activity 10.1 The present success rate in the treatment of a...
