I just finished a chapter on hypothesis tests in stats class. The problem is the following: On a standardized spatial skills task, normative data reveal that people on average get 15 correct solutions. A psychologist tests n=7 individuals who have brain injuries in the right cerebral hemisphere. For the following data, determine whether or not right-hemisphere damage results in significantly reduced performance on the spatial skills task. Test with alpha set at .05 with one tail. The data are as follows: 12,16,9,8,10,17,10.
We have to use the five step Hypothesis method 1.) State the hypothesis, 2.) Find the critical region, 3.) Calculate the test Statistic, 4.) State the decision, 5.) Write the conclusion.
Can you show your work (if possible) or just how you obtained the numbers? Can you also state the conclusion "There is significant evidence to show that....."? Any help on this question will be greatly appreciated. Thank you.
