Answer:
The value of c is [tex]c = 0.613[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 0[/tex]
The standard deviation is [tex]\sigma = 1[/tex]
[tex]P( z > c) = 0.27[/tex]
Generally From the z table the critical value corresponding to an area under the normal curve to the right with the value 0.27 is
[tex]c = 0.613[/tex]
