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]
