1. State the three methods of hypothesis test and explain on how you can use them to test a given claim.

2. Solve this problem using one of the methods for hypothesis test stated in question 1 above. Show all the steps required for the method you selected. A clinical trial was conducted to test the effectiveness of the drug zopiclone for treating insomnia in older subjects. Before treatment with zopiclone, 16 subjects had a mean wake time of 102.8 min. After treatment with zopiclone, the 16 subjects had a mean wake time of 98.9 min and a standard deviation of 42.3. Assume that the 16 sample values appear to be from a normally distributed population, and test the claim that after treatment with zopiclone, subjects have a mean wake time of less than 102.8 min. Does zopiclone appear to be effective?

Expert Solution

Conclusion - Zopiclone is not effective as p value > 0.05 PL??

SimpleLinkedBag We need to implement and test all of SimpleLinkedBag’s methods before we can use them in our game. These method implementations are similar to the examples in the course materials. When using the Node class, import it from the bag package. Refer to your text, class notes and examples to see examples of how to use a Node that holds a generic type. Remember the UML lists the return type for each method. SimpleLinkedBag() In SimpleLinkedBag, initialize the instance...

Whenever you are asked to test a hypothesis, be sure to: (a) state the null and alternative hypotheses; (b) state the relevant sample statistic; (c) give the rejection region; (d) compute the test; (e) give your decision and a conclusion in English. Assume that last year, licensed American drivers drove an average of 10,000 miles, with a standard deviation of 2,000 miles (these are population figures). This year, the government campaigned to get people to save gas by driving less. To test...
