the mean monthly income of trainees at a local mill is 1100 with a standard deviation of 150. find rthe probability that a train
Lunna [17]

Answer:

The  probability is  P(X <  900 ) =  0.0918

Step-by-step explanation:

From the question we are told that

   The sample mean is  \= x  = 1100

    The  standard deviation is  \sigma  =  150

     The random number value is  x =900

The probability that a trainee earn less than 900 a month is mathematically represented as

       P(X <  x) =  P(\frac{X -\= x}{\sigma}  <  \frac{x -\= x}{\sigma} )

Generally the z-value for the normal distribution is mathematically represented as

       z = \frac{x -\mu }{\sigma }

So From above we have

      P(X <  900 ) =  P(Z <  \frac{900 -1100}{150} )

      P(X <  900 ) =  P( Z

Now from the z-table

    P(X <  900 ) =  0.0918
