  3. How do you know if your hypothesis test is 1-tail or 2-tail?
  4. What is the critical value for a one-tailed hypothesis test in which a null hypothesis is tested at the 5% level of significance based on a sample size of 25?
    E) What are the critical values for a two-tailed test with a 0.01 level of significance when n is large and the population standard deviation is known?
    For questions F - H:
    Based on the Nielsen ratings, the local CBS affiliate claims its 11:00 PM newscast reaches 41% of the viewing audience in the area. In a survey of 100 viewers, 36% indicated that they watch the late evening news on this local CBS station. Is Nielson correct or not?
