The data below give the concentration of thiol (NM) in the blood lysate for two groups of volunteers. The first group of volunteers is considered 'normal', and the members of the second group of volunteers suffer from rheumatoid arthritis. Normal: 1.85 Rheumatoid: 2.81 1.90 2.85 2.35 4.08 1.45 3.95 1.83 3.27 1.92 3.77 Find the sample mean and sample standard deviation for the 'Normal' and 'Rheumatoid' groups, respectively. (Show the working steps.) 2.15 b Based on the result of (a), what kind of the hypothesis test should be used if we want to investigate whether the mean concentration of thiol is the same for the two groups?
