The shape is approximately normal and UF, – Hãz = 6. 5.
The shape is approximately normal and la, - µã, = -6. 5.
= -6.
The shape is approximately normal and U7, - Hã, = 5. 7.
The shape is approximately normal and la, - µã, = -5.7.
None of these is correct.
O The shape, mean, and standard deviation are all unknown.
