Question

Determine the area under the standard bormal curve that lies to the right of

(a) Z= -1.77, (b) Z=1.94, (c) Z=0.06, and (d) Z= -1.52

Answer 1

SOLUTION:

From given data,

Determine the area under the standard normal curve that lies to the right of

(a) Z= -1.77, (b) Z=1.94, (c) Z=0.06, and (d) Z= -1.52

(a) Z= -1.77

P (Z > -1.77) =  1- P(Z < -1.77) ( using z - table )

= 1 - 0.0384

= 0.9616

(b) Z=1.94

P (Z >1.94) =  1- P(Z < 1.94) ( using z - table )

= 1 - 0.9738

= 0.0262

(c) Z=0.06

P (Z >0.06) =  1- P(Z < 0.06) ( using z - table )

= 1 - 0.5239

=0.4761

(d) Z= -1.52

P (Z >-1.52) =  1- P(Z < -1.52) ( using z - table )

= 1 - 0.0643

= 0.9357
