In your attempt to “catch them all” you hunt the prized Pokemon, Mew and Mewtwo. As you battle them with your top 25 Pokemon, you lose every battle. However, after each battle, you notice that the hit points (HP) of Mew and Mewtwo have been reduced. The remaining HPs of Mew and Mewtwo are shown below after battling your respective Pokemon. (A higher HP remaining indicates more success in battle.) You suspect that Mewtwo is the tougher opponent, and you want to test this hypothesis at the 95% level of confidence.

e. Describe the Type II Error for this test, and explain its implication for you as you continue your quest.

f. What is the rejection region for this hypothesis test?

g. Calculate the test statistic for this hypothesis test. What is your conclusion?

h. If you reject the null hypothesis for this test, what is the probability that you have committed a Type I Error? (i.e., find the p-value for this test.)

i. What action will you take as you continue your quest based on your conclusion.

The day-to-day records of catch size were used to discover that the probability of a good fishing day being followed...
