Determine a deck of cards and remove kings. Ask the friend or family member to draw 3 cards. Ace signifies 1, Jack signifies 11, and Queen signifies 12. If you can't locate deck of cards, find the pair of dice, and roll them 3 times. If you don't have cards or dice, ask 3 friends to each select number between 1 and 12. In any of these cases, you will have three numbers. Write them down.
• Find out the mean for your 3 numbers. They signify your neighborhood's news-viewing habits. Mean is number of news programs viewed in neighborhood each week. Remember that you would typically have much larger sample size than 3.
• How did you believe that sample would compare to national mean? This is your hypothesis. Define either alternate or null hypothesis and recognize which one you are stating.
• Based on the hypothesis, would you use the one-tailed or two-tailed test? Describe why.
• Keep in mind that your sample was very small at 3. With sample of 3, your degrees of freedom would be 2. Suppose you could have sampled many more people in neighborhood. Post number of people you would really want to sample if you could. Let this your ideal N.
• Suppose that you had your ideal N. Your alpha level was .05. Select one or two-tailed test as suitable, and look up critical value of t. State the value in your post.
• What would you conclude if obtained t was larger than your critical t value, and what you conclude if your got was smaller than critical value?
