An animal geneticist is trying to pick an appropriate species of fish for repopulating a lake. He wants to compare how long certain types of fish live. Species A is used for a control group and Species B serves as the experimental group. A random sample of fish from both species is drawn and the following ages are recorded for life span in months.
a. State the nondirectional alternative hypothesis.
b. State the null hypothesis
c. Analyze the data with a nonparametric test. What do you conclude, using a = 0.05 2 tail ?
