The ______ hypothesis says that the difference between the samples shows a significant difference in the data. Given all other things to be equal, what p-value gives the most evidence for the null hypothesis? Given all other things to be equal, what p-value gives the most evidence for the alternative hypothesis? A p-value explains the percentage of chance that the null hypothesis is correct. A p-value is the chance of getting a big test statistic if the null hypothesis is correct. If the p-value is less than .05, the result is _______________. If the p-value is greater than .05, the result is __________________. If the p-value is .25, it best to say that the null hypothesis is ___________. If the p-value is .012, it is best to say that the null hypothesis is _____________. Can a p-value of .06 ever be considered statistically significant? Can a p-value of .25 ever be considered statistically significant? How long did it take you to complete this survey? |
