Question

The criteria for a decision regarding the value stated in a null hypothesis is set by the a. Probability b. P Value c. level of significance d. Both level of significance and P value

Answer 1

We decide, if we want to reject or fail to reject null hypothesis by using two methods. First is critical value method and second is p value method.

In the critical value method, we find table value across the level of significance using statistical table.

If calculated value > critical value, we reject null hypothesis.

In p value method, we find p value using test statistic and compare it with level of significance.

If p value < , we reject null hypothesis.

So here the correct option is d. Both level of significance and p value.
