(a)    

z = 2.00

(b)    

z = −1.75

(c)    

z = −2.60

(d)    

z = 0

(e)    

z = 1.96

Answer 1

A To find the properlion under the standand normal Curve that lies to the right of the values As we know whole area under standard normal curve is 1 & PC 272) is the padortion that lies to the night of the values. Now, PS Z>2} = 1-P{ 262] = 1 - $(2) = 1 -0.977 .0.023 6 P{ z>-1.753 = 1-PER = -1.75] - 1 € (-1.75) = $11.75) = 0.060 (21{2 > -2.60) = $(2.60) [As above] - 0.005 ( P{270) - 1-PE 250) = 2-8co) s 1-0.5 (1) PE 2 > 1967 - 1- P{ 2 2 1.6) = 1-001.go) = 1- 0.975 fere we get - 0.025 probabilities table all all probabilities from normal cumplatte
