1. How would you use the p-value to make a decision about the null hypothesis? 2. How is the p-value related to the test statistic? 3. Explain whether or not rejecting the null hypothesis makes the alternative hypothesis true and why. 4. 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?

Step 1
To make a decision about the null hypothesis using the p-value, we compare the p-value to the level of significance (alpha) set for the test. If the p-value is less than or equal to alpha, we reject the null hypothesis. If the p-value is greater than alpha, we Show more…

The p-value is calculated as p = 0.012 based on the test statistics. What is (are) the correct conclusion(s)? Select all correct conclusions. a) Reject the null hypothesis with alpha = 0.1 b) Reject the null hypothesis with alpha = 0.05 c) Reject the null hypothesis with alpha = 0.01 d) Reject the null hypothesis with alpha = 0.001

You perform a test of significance, using the hypotheses H₀: μ ≤ 5 VS. Hᐢ: μ > 5. If you obtain a p-value of 0.043, what will be your decision at 5% level of significance and why? Fail to reject the null hypothesis because p-value < 0.05 Reject the alternative because p-value < 0.05 Reject the null hypothesis because p-value < 0.05 Reject the null hypothesis because p-value > 0.05 Accept the null hypothesis because p-value < 0.05
