Which of the following statements about the p-value (or probability value) is correct?

  • A. None of these
  • B. If the p-value for a regression slope coefficient is 0 it means that the slope coefficient is significant
  • C. If the p-value is smaller than the level of significance we reject the null hypothesis
  • D. If the p-value is greater than the level of significance we reject the null hypothesis

For each of the following statements, identify whether the statement is true or false, and explain why. Please limit each response to no more than 3 sentences. i) A p-value is the probability that the null hypothesis is false. ii) A chi-square test statistic can never be negative. iii) If we reject the null hypothesis that a population proportion is equal to a specific value, then that specific value will not be contained in the associated confidence interval. iv) If...
