The time (in minutes) required to learn the procedure for performing a certain task is uniformly distributed on the interval fro
PtichkaEL [24]

Answer:

a

 P( X >  46)  = 0.7 \  minute

b

\mu  = 42 \ minute

Step-by-step explanation:

From the question we are told that  

   The procedure for performing a certain task is uniformly distributed on the interval from( a =  32 )minutes to (b= 52) minutes

  Generally the cumulative distribution function for continuous uniform distribution is  

             F(x) =  \left \{ {{0 \ \ \ \ \  for  \  x \  x < a} \atop {\frac{x-a}{b-a} } \ \   for \  a \le x \ge b} \atop {1 \ \ \ \ \ \ \  for  \  x  >  b }\right.

Generally the probability that it takes more than 46 minutes to learn the procedure is mathematically represented as

          P( X >  46)  = F(46) = \frac{46 - 32}{52-32}

=>       P( X >  46)  = 0.7 \  minute

Generally the average time required to learn the procedure is mathematically represented as

        \mu =  \frac{a + b}{2}

=>     \mu  =  \frac{32 + 52}{2}

=>     \mu  = 42 \ minute
