1/ In clinical trials of 3066 patients taking treatment A, 790 reported nausea as a side effect. In clinical trials of 1013 patients taking treatment B, 216 reported nausea as a side effect. Researchers want to know whether the difference in sample proportions is statistically significant. Use the "Randomization test for two proportions" applet in StatCrunch with a seed of 27371. Obtain exactly 3000 runs of the applet. What is the P-value based this randomization? P- value= (Round to four...
