Direction: Read and analyze the given problem. Supply the data being asked for on the items that follow. Effects of drug and alcohol on the nervous system have been the subject of significant research. A neurologist wants to test the effect of a drug by injecting 100 rats with a unit dose of the drug, subjecting each rat to stimulus, and recording its response time. It has been found out that = 1.05 and s = 0.50. The mean response time of a rat not to respond is 1.2 seconds with a standard deviation of 0.70. She wishes to test whether the mean response time for drug-injected rats differ from 1.2 seconds. Assume that the population is normal using a= 0.05, answer the following questions: 1. null and alternati ve hypothesis 2. test of hypothes is 3. level of significance 4. population standard deviation 5. sample standard deviation 6. number of se.mple 7. test statistic 8. critical value 9. rejection region 10. show the graph 11. decision 12. conclusion
