Question

The director of research and development is testing a new medicine. She wants to know if there is evidence at the 0.05 level that the medicine relleves pain in more than 335 seconds. After performing a hypothesis test, she decides to reject the null hypothesis What is the conclusion?

Answer 1

Here claim is that the medicine relieves pain in more than 335 seconds

As null hypothesis always have equality sign, hypothesis here is $H_0:\mu=335$ vs $H_1:\mu>335$

Further it is given that null hypothesis is rejected, hence we have sufficient evidence to support the claim that the medicine relieves pain in more than 335 seconds.

So conclusion is that the claim that medicine relieves pain in more than 335 seconds is true.
