Answer:

a) 0.356

b) 0.429

c) 0.773

d) 0.107

Step-by-step explanation:

We have to determine the area on the left of the given z-statistic.

We calculate the p-value from the standard normal table and give the area under the graph.

(a) Z = -0.37

[tex][P( z < -0.37) = 0.356 = 35.6\%[/tex]

(b) Z = -0.18

[tex][P( z < -0.18) = 0.429 = 42.9\%[/tex]

(c) Z = 0.75

[tex][P( z < 0.75) = 0.773 = 77.3\%[/tex]

(d) Z = - 1.24

[tex][P( z < -1.24) = 0.107 = 10.7\%[/tex]
