Nationally, patients who go to the emergency room wait an average of 7 hours to be admitted into the hospital. Do patients at rural hospitals have a lower waiting time? The 10 randomly selected patients who went to the emergency room at rural hospitals waited an average of 6.2 hours to be admitted into the hospital. The standard deviation for these 10 patients was 2.5 hours. What can be concluded at the the αα = 0.01 level of significance level...

A hospital administrator wants to determine the proportion of emergency room patients that use the emergency room (ER) for non-emergency care. She randomly samples records from 350 ER patients and determines that 74 of those patients required only non-emergency care. 1. The administrator constructs a 90% confidence interval for the true proportion of all ER patients who use the ER for non-emergency care. The error bound for the proportion EBP for this confidence interval is: A. 0.036 B. 0.072 C....

Hospital administrators wanted to understand and better control the waiting time of patients in the emergency room (ER) department. To do this, they constructed x-bar and R-charts by sampling the waiting times of the first five patients admitted to the ER at the beginning of each shift (7 a.m., 3 p.m., and 11 p.m.). 1. What do you think of this approach? 2. Will it provide the information the hospital administrators seek? 3. How might the sampling process be improved,...
