Question
Describe one-tailed p-values.
Expert Solution

Step 1
The choice of a specific value of the level of significance is completely subjective and hence the testing procedure and the critical value might change based on the level of significance.We then calculate p-value,which is always fixed,no matter what the level of significance will be.The p-value associated with a test is probability that we obtain the observed value of the test statistic or a value that is more extreme in the direction given by the alternative hypothesis when the null hypothesis is true.
