A bright surgeon claims that she found a new technique that reduces patient mortality in a certain brain tumor removal operation. The surgeon shares the data she and her teammates collected over 5- years using this new method. A total of 10 surgeons have applied this technique and over the course of 5-years their scores of follow-up annual patient mortality counts are Xi : 1, 2, 1, 0,1,2,1,3,0,1 Knowing that the traditional method has an average follow-up annual mortality count of 2, can the surgeon say her technique is superior to the traditional technique?

A. Identify the appropriate statistical procedure to apply.

B.Conduct the test. Make a decision about the null hypothesis, interpret your results and calculate effect size if applicable. At ??= .05 does the surgeon have a reasonable right to say that her technique is superior to the traditional technique?
