Question: A drug company wishes to compare the effects of three
A drug company wishes to compare the effects of three different drugs (X, Y, and Z) that are being developed to reduce cholesterol levels. Each drug is administered to six patients at the recommended dosage for six months. At the end of this period the reduction in cholesterol level is recorded for each patient. The results are given in Table 11.14. Using these data we obtain SSTO = 2547.8, SSE = 395.7, X-barx = 23.67, X-bary = 39.17, and X-barz = 12.50. Completely analyze these data using one- way ANOVA.
