The tаble belоw shоws the number оf hours per dаy 11 pаtients suffered from headaches before and after 7 weeks of soft tissue therapy. At α=​0.01, is there enough evidence to conclude that soft tissue therapy helps to reduce the length of time patients suffer from​ headaches? Assume the samples are random and​ dependent, and the population is normally distributed. (This is a multi-part problem. You will be working with this dataset for Problems 25, 26, 27, and 28.)  Patient 1 2 3 4 5 6 7 8 9 10 11 Daily headache hours (before) 2.7 3.5 2.3 2.8 2.8 2.5 3.5 3.4 4.4 4.2 2.3 Daily headache hours (after) 1.5 2.6 1.9 1.6 2.1 1.1 2.4 1.6 1.1 2.6 1.6 Identify the correct null and alternative hypothesis statements based on the problem above.  Let  μ D be the hypothesized mean of the patients' daily headache hours before therapy minus their daily headache hours after it.
