Question

Dr. Harmon expected that her neurotic patients would come significantly earlier to all scheduled appointments compared to other patients, and planned to run a one-tailed test to see if their arrival times were much earlier. Unfortunately, she found the opposite result: the neurotic patients came to appointments later than other patients. What can Dr. Harmon conclude from her one-tailed test?

a) There is no evidence that neurotic patients come to appointments significantly earlier than other patients.

  

b) Neurotic patients come to appointments significantly earlier than other patients.

  

c) Neurotic patients come to appointments significantly later than other patients.

d) Non-neurotic patients come to appointments significantly earlier than neurotic patients.

Answer 1

it is given that a one tailed test is used to test the claim whether neurotic patients come to appointments significantly earlier than other patients.

Null hypothesis:- neurotic patients come to appointments at the same time as compared to other patients.

Alternate hypothesis :- neurotic patients come to appointments significantly earlier than other patients.

Result shows that the neurotic patients come to appointments later than other patients, this provides sufficient evidence for us to fail to reject the null hypothesis

We can say that the result is not supporting the alternate hypothesis that neurotic patients come to appointments significantly earlier than other patients.

So, we can say that there is insufficient evidence to support the alternate hypothesis that neurotic patients come to appointments significantly earlier than other patients.

option A is most appropriate answer
