Question

The administrator at your local hospital states that on weekends the average wait time for emergency room visits is 10 minutes. Based on discussions you have had with friends who have complained on how long they waited to Be seen in the ER over a weekend, you dispute the administrators claim. Over the course of a few weekends, you record the wait time for 40 randomly selected patients. The average wait time for these 40 patients as 11 minutes with a standard deviation of three minutes. Do you have enough evidence to support your hypothesis that the average ER wait time exceeds 10 minutes? You opt to conduct the test at a 5% level of significance. 

 

  1. d) calculate (formula /values) The test statistic and the associated P value range from the table 

 

  1. e) State the decision of the test 

 

  1. f) Express your conclusion concisely using statistically appropriate language applied to the ER wait time 

 

  1. g) determine the point estimate of the population mean  

 

  1. h) specify the confidence interval
Yes the condition are sufficiently met to perform a
task.
Part b
One sample T-test type of test we use.
Part c
The null hypothesis is
Но : и 3D 10
And the alternative hypothesis is
На : и > 10
Therefore it is right tailed.
