Length of Stay - Health insurers and federal government are both putting pressure on hospitals to shorten the average length of stay (LOS) of their patients. The average LOS for women is 4.55 days according to Statistical Abstract of the United States: 2005. A first study conducted on a random sample of 25 hospitals in Michigan had a mean LOS for women of 3.8 days and a standard deviation of 1.15 days. A medical researcher wants to determine if the mean LOS for women in Michigan is less than 4.55 days. The null and alternative hypothesis are given by = 4.55 vs HẠ: µ < 4.55. rl : °H What is the estimated effect size d? Give your answer to 4 decimal places.
