Answer:
The probability that the mean monitor life would be greater than 96.3 months in a sample of 84 monitors
 P(X⁻ ≥ 96.3) = 0.0087
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the mean of the Population = 95
Given that the standard deviation of the Population = 5
Let 'X' be the random variable in a normal distribution
Let X⁻ = 96.3
Given that the size 'n' = 84 monitors
<u><em>Step(ii):-</em></u>
<u><em>The Empirical rule</em></u>
          
         
        Z = 2.383
The probability that the mean monitor life would be greater than 96.3 months in a sample of 84 monitors
     P(X⁻ ≥ 96.3) = P(Z≥2.383)
                       =  1- P( Z<2.383)
                       =  1-( 0.5 -+A(2.38))
                       = 0.5 - A(2.38)
                      = 0.5 -0.4913
                     = 0.0087
<u><em>Final answer:-</em></u>
The probability that the mean monitor life would be greater than 96.3 months in a sample of 84 monitors
 P(X⁻ ≥ 96.3) = 0.0087
