Question
I suspect that my pet dog Woof can predict the outcome of international soccer matches. I place two balls infront of Woof, the red ball represents one team and the blue ball represents the opposition. Woof picks up one of the two balls, the ball he picks up is the team he predicts to win the soccer match. My assertion that he can predict the outcome of matches comes from the the observation that he correctly predicted the outcome of four consecutive soccer matches last weekend. It is known that the probability that a dog can just randomly predict correctly the outcome of four consecutive soccer matches is 6.25% (ie. the probability of correctly predicting the outcome of three consecutive soccer matches by just random chance is 6.25%). which statement is/are correct? (C) This is an example of biased reporting. If I wait long enough (and Woof has a very long life), by random chance he will be able to correctly predict the outcome of 3 or more consecutive soccer matches (even 20 consecutive soccer matches!). (B)If we test the hypothesis that Ho: woof has predictive abilities against HA Woof has NO predictive abilities, we see that the p value is 6.25%, as this is greater than 5% we can reject the null. This proves that my dog has no predictive abilities. (A If we test the hypothesis that Ho: woof has N predictive abilities against H W of has predictive abilities e see that the p al e s 5% is greater an the 6significance level is predictions can easily be explained by random chance, though it does not prove that Woof has no predictive abilities. (B) and (C) are correct. (A) and (C) are correct Question Details My Notes Ask Your Teacher The 95% confidence interval or the mean change in polypheno e els a ter drinking one glass of red wine even, n ght over a month period the hypothesis H041-0 against HAM * 0 . what are the results of the test done at the 5% significance level? ake after minus before s s you use isto est The p-value is LESS than 5%, thus we can reject the null at the 5% level The p-value is greater than 2.5%, but it is unknown whether it is less than 5% level. So we do not know the results of the test at the 5% level. However, we CANNOT reject the null at the 1% level. Since 0 lies in the 95% interval, the p-value is greater than 5% and we CANNOT reject the null at the 5% levelExplanation / Answer

Our hypothesis will be:
Ho: Wolf has no predictive abilities.
Ha: Wolf has predictive ability
p - value = 0.0625
So we do not reject Ho at 5% level.
Hence,
Only (A) is correct.

Option 3rd is correct.
