In a test of H0: µ = 100 against Ha: µ > 100, a sample of size 80 produces z = 0.8 for the value of the test statistic. The P-value of the test is thus equal to . 0.20 0.40 0.29 0.42 (e) 0.21. 3. A certain population follows a Normal distribution with mean and standard deviation .

P-Value Definition
P-value Approach to Hypothesis Testing. The . p-value. associated with the observed value of the test statistic is the probability of getting the observed value or a value more extreme (in the direction of Ha), assuming H0 is true. The p-value represents the probability of observing a sample outcome more contradictory to H0 than the observed ...

The P-value (or “observed significance level”) of a test is the probability of observing as extreme (or more extreme) of a value of the test statistic than we did observe, if H0 was in fact true. The P-value gives us an indication of the strength of evidence against H0 (and for Ha) in the sample.

A large chi-square test statistic results in a large p-value. A large p-value means that there is a good chance that the relationship is statistically significant. If the two variables are not related in the population, then less than 5% of the samples you could ever take would give you a test statistic of 3.84 or larger.

Otherwise we use the t test statistic and the sample standard deviation (s); the t statistic has degrees of freedom (df) = n – 1. Compute the value of the appropriate test statistic. Calculate the p-value of the test statistic. This is done using Excel or computer software. We …

(6 points) For the story above, state the hypotheses, calculate the test statistic and P-value (using the Normal table from the course webpage or your book), and state your conclusion in terms of the story. Be sure to state whether your conclusion refers to the population or the sample.

4. What do we know about the P-value for testing the null hypothesis that the probability of complaining is the same for the United States and Puerto Rico? A) P-value < 0.010. B) 0.010 < P-value < 0.025. C) 0.025 < P-value < 0.05. D) This cannot be determined, because these are not the hypotheses being tested by the chi-square test.

P-value : The probability that the test statistic will take on a value that is at least as extreme as the observed value of the statistics when the null hypothesis is true. It is the smallest level of significance at which the null hypothesis would be rejected.
