The table below shows the number of hours per day 11 patients
suffered from headaches before and after 7 weeks of soft tissue
therapy. At alphaαequals= 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. Complete
