A new automated procedure for determining glucose in serum (Method A) is to be compared to the established method (Method B). Both methods are performed on serum from the same six patients in order to eliminate patient to patient variability. Do the following results confirm a difference in the two methods at the 95% confidence level? Patient 1 Patient 2 Patient 3 Patient 4 Patient 5 Patient 6 Method A glucose mg/L 1044 720 845 800 957 650 Method B glucose mg/L 1028 711 820 795 935 639 Difference mg/L . State the null hypothesis, Ho Calculate mean difference d (d-bar) = Calculate std deviation of the mean, So = State the alternative hypothesis, Ha Look up t in the table for a dof = tab = and determine the rejection region. Solve for t calculated =
