Length of Stay ~ Health insurers and federal government are both putting pressureon hospitals to shorten the average length of stay (LOS) of their patients. Theaverage LOS for women is 4.55 days according to Statistical Abstract of the UnitedStates: 2005.A first study conducted on a random sample of 25 hospitals in Michigan had a meanLOS for women of 3.8 days and a standard deviation of 1.15 days.A medical researcher wants to determine the sample size required to estimate themean LOS for women in Michigan at 95% confidence with a margin of error of nomore than 0.25 using the following formula,(嘉)。.t*SпМЕWhat is the value of the t* multiplier you would substitute in the formula above?Give your answer to 4 decimal places.Your Answer:Answer
