One-tailed tests - ANSWERSA hypothesis test in which rejection of the null hypothesis occurs for values of the test statistic in one tail of its sampling distribution. null hypothesis - ANSWERSThe hypothesis tentatively assumed true in the hypothesis testing procedure. alternative hypothesis - ANSWERSThe hypothesis concluded to be true if the null hypothesis is rejected. Type II error - ANSWERSThe error of accepting H0 when it is false. Type I error - ANSWERSThe error of rejecting H0...

As the test statistic becomes larger, the p-value: - CORRECT ANSWER-becomes smaller. The probability of making a Type I error when the null hypothesis is true as an equality is called the: - CORRECT ANSWER-level of significance. In hypothesis testing, the tentative assumption about the population parameter is called: - CORRECT ANSWER-the null hypothesis. The p-value: - CORRECT ANSWER-must be a number between 0 and 1. For a two-tailed test, the p-value is the probability of obtaining ...
