Help! (b) What is the correct P-value for z =2.24?O 0.006250.05000.03750.0250 Researchers are interested in the effect of a high-protein diet on the performance of undergraduates on the Verbal GRE.They start with no expectations as to whether students on the high-protein diet will perform better than students in acontrolgroupwho follow their usual diet. After noticing that students on the high-protein diet tended to have higher GREscores, the researchers decided to test a one-sided alternative about the mean Verbal GRE scores,Ho : Mnigh-protein diet= Hcontrol dietHa : Mhigh-protein diet > Mcontrol dietThe researchers find z = 2.24 with one-sided P-value is P = 0.0125.(a) Explain why the researchers should have used the two-sided alternative hypothesis.The researchers selected the alternative hypothesis after examining the data. The alternative hypothesis should beformulated before examining data, and should be motivated by data.The researchers selected the alternative hypothesis after examining the data. The alternative hypothesis should beformulated before examining data, and espcially should not be motivated by data.The researchers selected the alternative hypothesis before examining the data. The alternative hypothesis should beformulated after examining data, and should be motivated by data.The researchers selected the alternative hypothesis before examining the data. The alternative hypothesis should beformulated after examining data, and especially should not be motivated by data.
