Question 1140431
From the cumulative normal distribution table, 

{{{P(z <= 2.00) = 0.97725}}}.

{{{P(z < -2.00)}}}
= {{{1 - P(z >= -2.00)}}}
= {{{1 - P(z <= 2.00) }}}.....by symmetry of the normal distribution
= {{{1 - 0.97725}}}
 = {{{0.02275}}}


{{{P(-2.00 <= z <= 2.00)}}}
= {{{P(z <= 2.00) - P(z < -2.00)}}}
= {{{0.97725 - 0.02275}}}
= {{{0.9545 }}}->answer

{{{P(-2.00 <= z <= +2.00)=0.9545 }}}
