The sample mean hospitalization cost for the control 13 lestion group is 3200 dollars with a sample standard deviation of 1245 dollars. The sample mean hospitalization cost for the geriatric team care" is 2680 dollars with a sample standard deviation of 1160 dollars. 19 (a) What are the null and alternative hypotheses? 0 Finis p HA: P = 4 0 (b) What is the test statistic?
