1. List the 4 steps that are used for hypothesis testing.

5. A random survey of 75 death row inmates revealed that the mean length of time on death row is 17.4 years with a standard deviation of 6.3 years. If you were conducting a hypothesis test to determine if the population mean time on death row could likely be 15 years, what would the null and alternative hypotheses be?

7. In a population of fish, approximately 47% are female. A test is conducted to see if, in fact, the proportion is less. State the null and alternative hypotheses.
