Question
The table below shows the number of hours per day 11 patients suffered from headaches before and after 7 weeks of soft tissue therasy. At a=0.01, is there enough evidence patients suffer from headaches? Assume the samples are random and dependent, and the population Patient Daily headache hours (before) 2.9 3.2 3.4 1.8 4.4 1.8 3.8 2.5 1.8 3.3 3.8 Dally headache hours (after) 1.7 3.6 conclude that soft tissue therapy helps to reduce the length of time normally distributed. Complete parts (a) through (f). 1 2 3 456 789 10 11 0 2.2 1.1 1.1 1.4 3.5 2.2 1.2 2.9 4.3 (a) Identify the claim and state Ho and Ha- The claim is "The therapy helps to reduce the length of time patients suffer from headaches." Let Ha be the hypothesized mean of the patients' daily headache hours before therapy minus their daily headache hours after it. State Ho and H. Choose the correct answer below. OA. Ho: Ha sd B.
