question 25

Nationally, patients who go to the emergency room wait an average of 5 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 3.8 hours to be admitted into the hospital. The standard deviation for these 10 patients was 2 hours.

1. The p-value is     α?


2. Based on this, we should  reject or fail to reject     the null hypothesis.?


3. Thus, the final conclusion is that ...(choose 1 correct answer )
   
   
   

   
   
   • The data suggest that the population mean awaiting time to be admitted into the hospital from the emergency room for patients at rural hospitals is notsignificantly lower than 5 hours at αα = 0.01, so there is statistically insignificant evidence to conclude that the population mean waiting time to be admitted into the hospital from the emergency room for patients at rural hospitals is lower than 5 hours.
   
   
   • The data suggest the population mean is notsignificantly lower than 5 at αα = 0.01, so there is statistically insignificant evidence to conclude that the population mean waiting time to be admitted into the hospital from the emergency room for patients at rural hospitals is equal to 5 hours.
   
   
   • The data suggest the populaton mean issignificantly lower than 5 at αα = 0.01, so there is statistically significant evidence to conclude that the population mean waiting time to be admitted into the hospital from the emergency room for patients at rural hospitals is lower than 5 hours.
