p-value: We can reject this null hypothesis at any reasonable level. 10. A wine producer claims that the proportion of its customers who cannot distinguish its product from frozen grape juice is at most 0.10. The producer decides to test this null hypothesis against the alternative that the true proportion is …

do not reject the null hypothesis. The p-value and α are related, but are different concepts. As we shall see, we fix α in advance, but the value of p depends on the result of our study. The term . statistical significance. is used somewhat inconsistently to refer either to α or to the p-value. 2. The p-Value Approach to Hypothesis Testing. There are two different conventions for statistical hypothesis testing under the classical paradigm: the p-value …

The P-value gives us an indication of the strength of evidence against H0 (and for Ha) in the sample. This is a different (yet equivalent) way to decide whether to reject the null hypothesis: • A small p-value (less than ) = strong evidence against the null => Reject H0

Usually, researchers will reject a hypothesis if the p-value is less than α = 0.05. Sometimes researchers will use a stricter cut-off (e.g., α = 0.01) or sometimes researchers will use a more liberal cut-off (e.g., α …

If the null hypothesis were true, the P-value of a sample tells you how often you’d expect to find a random sample that is as weird (or weirder) than yours. If the null hypothesis were true, α tells us the fraction of the samples for which we’re (incorrectly) going to reject the null hypothesis.
