D Question 10 12 pts What is a p-value? Suppose a t test of independent means at 95% confidence comparing the financial returns of two groups of investors, with each group using a different strategy, shows a p-value of 0.2292 (null hypothesis: the two strategies have the same average returns). Which of the following is true? the p-value tells us that we are absolutely certain that the stragies have the same outcome O O the p-value tells us that there is strong evidence that the strategies have the same outcome 0 the p-value tells us that we have no particular evidence in this case O the p-value tells us that there is strong evidence that the strategies have different outcomes the p-value tells us that we are absolutely certain that the strategies have different outcomes

Explanation / Answer

The P value obtained is greater than 5% significant value. Therefore we do have enough evidence to reject null hypothesis . Therefore we conclude that the two strategies have same outcome. Therfore it is option 2.
