11. Use special features of TI-calculator to find the probabilities for given z-scores or to calculate z- scores for given probabilities. Label the axis with proper variable and shade the corresponding areas (it is a part of the score). Show your work in form: P(?)=normalcdf (Zmin, Zmax, Hz, 62)=answer or z= invNorm (Area, Hz, 62)=answer. (a) P(z 1.96)= (c) For what z-score P(z > ?) = 0.6915? (d) For what z-scores middle P(?
