What is a p-value and how is it used to make a decision about the null hypothesis? How is the p-value related to the test statistic? Explain whether or not rejecting the null hypothesis makes the alternative hypothesis true and why. If I conduct a hypothesis testing with Type I error set at 0.05 and a resulting p-value of 0.3, what would my conclusion be?

Consider the following. (a) For the same data and null hypothesis, is the P-value of a one-tailed test (right or left) larger or smaller than that of a two-tailed test? Explain your answer. The P-value for a one-tailed test is smaller because the two-tailed test includes the area in only one tail.The P-value for a one-tailed test is smaller because the two-tailed test includes the area in both tails.     The P-value for a one-tailed test is larger because the two-tailed test...
