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.

p-value = 0.1814. p-value is not less than alpha. So, we fail to reject Ho. 61. B The assumptions of the hypothesis test for a proportion are the data must be categorical, data must come from a random sample, np> 15 and n(1-p)> 15.

P-Value = P(z > 2.063) = 0.0196. Conclusion: We reject Ho b/c the P-Value of 0.0196 is less than alpha = 0.05. We have sufficient evidence that the true proportion of males that are colorblind is greater than for females. Interpret the P-value in this context.

When asked to explain the meaning of “the P-value was P = 0.03”, a student says, “This. means there is only a 3% chance that the null hypothesis is true.” Is this a correct explanation? Explain. Randomly selected statistics students participated in an experiment to test their ability to . determine when 1 min (60 seconds) has passed.

The estimator for p is . Test statistics: Decision can be made in one of the two ways: Let z* be the computed test statistic values. Lower tailed test P-value = P(zz*) Two-tailed test P-value = 2P(z > |z*| )=2P(z
