Sir
If only mean and SD given then how calcultion the above

[@CommerceandManagement]

Number of items in the series are also required. If you have any such question then you can send it through email.

Sir S.D hai ye variance nahi use square root

[@CommerceandManagement]

Kaha pr use karna hai square root?

[@AshaAsha-rc2or]
