I need help with statistics...?

Question

Let Z be a standard normal random variable.

P(-c (is less than or equal to) Z (is less than or equal to) c)=.9736

Answer 1

P( -c ≤ Z ≤ c ) = 0.9736

this mean P( |Z| > c ) = 1 - 0.9736 = 0.0264

P(Z > c ) = 0.0264/2 = 0.0132

P( Z < -c) = 0.0132

c = 2.22
