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 4.5774 days according to Statistical Abstract of the United States: 2005.

A first study conducted on a random sample of 18 hospitals in Michigan had a mean LOS for women of 3.8911 days and a standard deviation of 1.2279 days.

A medical researcher wants to determine if the mean LOS for women in Michigan is less than 4.5774 days. The null and alternative hypothesis are given by

H0: μ = 4.5774 u< 2.5774

Note: Numbers are randomized for each instance of this question. Use the numbers given above.

What is the estimated effect size dˆ? Give your answer to 4 decimal places.
