If z∼N(0,1) then" cod.f. "F(z)=P(z <= z^(**))A standard normal table gives the less thon equal to probabilities.a) p(z < z^(***))=0.025. From a standard normal tablep(7 < -1.96)~~0.025=>z^(**)=-1.96b) p(z < z^(**))=0,0098But, P(z < -2.33)~~0.0098=>z^(**)=-2.33{:[" c) "P(z < z^(**))=0.0506],[:'P*(z < -1.64)~~0.0506=>z^(**)=-1.64]:}{:[" d) "P(z > z^(**))=0.0195],[=>1-P(z < z^(**))=0.9805],[=>P(z < ...
