Given: 95%; n = 11; σ is known; population appears to be very skewed.
Do one of the following as appropriate:
( a ) find the critical value zα/2
( b ) find the critical value tα/2
( c ) state that neither the normal nor the t distribution applies

Both the Normal and the T-distribution assume an approximate bell-shaped curve. Since this population appears to be very skewed, state that neither the normal nor the t distribution applies
Hope that helps
