Answer #1

P value help us retain or reject null hypothesis H0 .So let us understand this by examples .

Example 1: Suppose you have level of significance .Then the P value you obtained is SMALLER than the level of significance therefore result is SIGNIFICANT and you REJECT THE NULL HYPOTHESIS H0.

Example 2: Suppose you have level of significance .Then the P value you obtained is GREATER than the level of significance therefore result is NOT SIGNIFICANT and in this case you DO NOT REJECT THE NULL HYPOTHESIS H0.

A researcher doing a paired T Test obtains a p-value of 0.026 when testing the hypotheses H0:ud = 0 and Ha: ud =/ 0. If she also computes a 99% confidence interval for the mean difference, which of the following should she expect? Answers: Zero will be in the confidence interval because 0.026 < 0.05 Zero will not be in the confidence interval because 0.026 > 0.01 Zero will not be in the confidence interval because 0.026 < 0.05 Zero...
