Answer:
Step-by-step explanation:
In a two tailed test the probability of occurrence is the total area under the critical range of values on both the sides of the curve (negative side and positive side)
Thus, the probability values for a two tailed test as compared to a one tailed test is given by the under given relation -
\
Here
Substituting the given value in above equation, we get -
probability values for a two tailed test
