Explanation / Answer

Well to determine whether the test is two tailed ,right tailed or left tailed .. one should look at alternative hypothesis ..

E.g. Ho u=4.0

H1 u>4.0 then it is called right tailed test

If H1 u<4.0 then it is called left tailed test

And if H1 u is not=4.0 then it is called two tailed because it can be both side i.e. u<4.0 ,u>4.0 ..

Hence in our case Ho p=0.94 vs H1 p is not =0.94

Hence two tailed test
