The Rheumatology Clinic has five defined treatment protocols for treating a specific form of fibromyalgia. They are trying to determine if patients experience a similar response to pain from the disease when using a specific treatment protocol. They asked patients to provide a score of 1 to 10 to describe their level of pain over the past week and captured the data by treatment. A value of one means that patient experienced little to no pain and a value of 10 means that the patient experienced extreme pain. The response data is provided in the Pain Data tab.

How do I do a two-sample t-test to determine if the mean level of reported pain for Treatment 3 is equal to the mean level of reported pain for Treatment 4.

Null Hypothesis: m₃ = m₄

Alternative Hypothesis: m₃ m₄

What is the p-value from this t-test?
