Researchers fed mice a specific amount of Toxaphene, a poisonous pesticide, and studied their nervous systems to find out why Toxaphene causes tremors. The absolute refractory period, time required for nerves to recover after a stimulus, was measured and varies Normally. The measurements, in milliseconds, for five mice were 1.8, 1.9, 2.0, 2.1, and 2.3. Part A: Find the mean refractory period and the standard error of the mean. Part B: Suppose the mean absolute refractory period for unpoisoned mice is known to be 1.85 milliseconds. Toxaphene poisoning should slow nerve recovery and therefore increase this period. Does the data give good evidence at a significance level of 0.10 to support this theory? What can you conclude from a hypothesis test? Justify your response with statistical reasoning.
