Conclusion based off p-value?
Since the p-value is 6.2e-09 then we have strong evidence to
reject the null hypothesis. Is this correct or do we fail to make a
conclusion because the validity conditions are not met?
Also a follow up question is:
If the validity conditions for the two-sample or paired
t-tests are not met, what kind of tests can you do?

Question 20 Not yet answered Points out of 8.00 Here is some output from R Studio. This is data is on mice and a new drug that helped with preventing early death in mice. The researcher was interested in its effects on the weights of the mice. The data is based on 10 mice that received the treatment. Research question: Does the weight of the mice increase significantly after the 3 months of the treatment? Write a conclusion based on the output evaluating the p-value in the context of the study.
