Answer 1

Solution :

Given that,  

Using standard normal table ,

QUESTION 24

P(z > -0.23) = 1 - P(z < -0.23) = 1 - 0.406 = 0.5910

option c. is correct

QUESTION 25

P(z > 0.44) = 1 - P(z < 0.44) = 1 - 0.67 = 0.3300

option A. is correct

QUESTION 26

P(-1.82 < z < -0.68)

= P(z < -0.68) - P(z < -1.82)

= 0.2483 - 0.0344

= 0.2139

P(-1.82 < z < -0.68) = 0.2139

option D. is correct
