Question

Please select the best statement about a statistical hypothesis test. 1.If the P-value is less than 0.1, then we can say that without a doubt, the null hypothesis must be incorrect. 2.The null hypothesis is a statistical hypothesis that what we see cannot be explained by chance. 3.The P-value is the probability of obtaining a test statistic result at least as extreme as the one that was actually observed, assuming the null hypothesis is true. 4.The alternative hypothesis is a statistical hypothesis that nothing interesting has happened. What we see is due to chance.
