  • Please state the null and alternative hypotheses.
  • Using an alpha level of .05, please test the null hypothesis (what is the appropriate test, what is the critical value?). Draw the rejection region.
  • Calculate the test statistic
  • State the conclusion you are entitled to draw as a result of this test.
  • Calculate the effect size as appropriate for the hypothesis test used.

  1. A current popular game relies on the rolling of twenty sided dice to determine success or failure. The current iteration occasionally uses rolling two dice, but only selecting the best roll to determine the outcome. An older edition merely modified the roll by 2 during these occasions. A sample of rolls under both conventions has been collected. The mean of 10 rolls using the two dice technique was 13.9 (SD = 3.8). The mean of 10 rolls using the older technique was 12.5 (SD = 4.4). Does the revised technique make a difference?
