Explanation / Answer

Dear Student, please post one question at a time. Thanks..

Solution of 11:

There are 3 groups and test should be conducted as to whether all 3 groups have the same means.

t test can be used only for comparison of two means.

z test also only for comparison of two means.

Hence here F test will be the correct test to use.

Please rate me if its help. Thanks in advance.
