An anger-management course claims that, after completing its seminar, participants will lose their tempers less often. Aways a skeptic you decide to test this claim. A random sample of 12 seminar participants is chosen, and these participants are asked to record the number of times that they lost their tempers in the two weeks prior to the course. After the course is over, the same participants are asked to record the number of times that they lost their tempers in the next two weeks. The following table lists the results of the survey. Using these data, test the claim at the 0.02 level of significance assuming that the population distribution of the paired differences is approximately normal.

Coal is carried from a mine in West Virginia to a power plan in New York in hopper cars on a long train. Suppose the weight of the coal in one car was less than 74.5 tons. Would that fact make you suspect that the loader had slipped out adjustment? Suppose the weight of the coal cars selected at random had an average x bar of less than 74.5 tons. Would that fact make you suspect that the loader had slipped out of adjustment why?
(DO NOT use any other symbol except numbers in the answer slot ) In an experiment, you flipped one coin and rolled three dice followed by the coin-flipping. An outcome of this experiment will look like (H,4,5,2) for an example . [T= Tail, H=Head] i. How many possible outcomes (like mentioned above) can be there from this experiment? ii. No matter what the coin shows, how many outcomes are there where all of the dice show different numbers ?

When people learn a new task, their performance usually improves when they are tested the next day, but only if they get 6 hours sleep (Sticckgold, et al., 2000). The following data demonstrate this phenomenon. The participants learned a visual discrimination task on one day. Half of the participants were allowed to have at least 6 hours of sleep and the other half were kept awake all night. 6 hours sleep No sleep n =14 n = 14 M = 72 M = 65 SS = 932 SS = 706 Will the 6-hour sleep show a much higher performance rate? This time use a one-tail with alpha = .05 Show all of the steps. Remember use the attached t-distribution chart when obtaining your critical region.
