Activity 5. Do It Now! Directions: Read and analyze the given problem. Supply the data being asked for on the items that follow. 1. Eifects of drug and alcohol on the nervous system have been the subject of signicant 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 the mean is i = 1.05 with standard deviation of s = 0.5. The mean response time of a rat not to respond is 1.2 seconds. She wishes to test whether the mean response time for drug-injected rats differs from 1.2 seconds. Assume that the population is normal using a = 0.05. a. null and alternative hypotheses: b. test of hypothesis: c. level of significance: d. population standard deviation: e. sample standard deviation: f. number or sample: g. test statistic: h. critical value: i. rejection region: j. graph:
