1. (5%) A new automated procedure for determining glucose in serum (Method A) is to be compared with the established method (Method B). Both methods are performed on serum from the sarne six patients to eliminate patient-to-patient variability. Do the following results confirm a difference in the two methods at the 95% confidence level?

2. (5%) The analysis of a calcite sample yielded CaO percentages of 55.95, 56.00, 56.04, 56.08, and 56.23. The last value appears anomalous; should it be retained or rejected at the 95% confidence level? (To answer this question, please refer to the statistics table at the bottom of this page.)
#445337
3. (10%) A 0.9092-g sample of a wheat flour was analyzed by the Kjeldahl method. The ammonia formed was distilled into 50.00 mL of 0.05063 M HCl; a 7.46-mL back-titration with 0.04917 M NaOH was required. Calculate the percent of protein in the flour. (Note: The nitrogen-to-protein conversion factor for cereals is 5.7)
